Alexandrite gemstone

Alexandrite is named after the Russian tsar Alexander II (1818-1881), the very first crystals having been discovered in April 1834 in the emerald mines near the Tokovaya River in the Urals. The discovery was made on the day the future tsar came of age. Although alexandrite is a relatively young gemstone, it certainly has a noble history. Since it shows both red and green, the principal colours of old Imperial Russia, it inevitably became the national stone of tsarist Russia.Beautiful alexandrite in top quality, however, is very rare indeed and hardly ever used in modern jewellery. In antique Russian jewellery you may come across it with a little luck, since Russian master jewellers loved this stone. Tiffany’s master gemologist George Frederick Kunz (1856-1932) was also fascinated by alexandrite, and the jeweller’s firm produced some beautiful series of rings and platinum ensembles at the end of the 19th and beginning of the 20th century. Smaller alexandrites were occasionally also used in Victorian jewellery from England.

Alexandrite is the rare colour-change variety of the mineral chrysoberyl . Its rarity is a result of its unlikely chemical makeup. Alexandrite can only form when aluminium and beryllium combine with trace elements like iron, titanium and, most importantly, chromium. On rare occasion, vanadium may also be present. The unlikelihood of the rare element chromium being in the right place to combine with aluminium and beryllium under exactly the right conditions to create alexandrite is what makes it so rare and valuable

The magic of converting colorations.

The most sensational characteristic approximately this stone, however, is its unexpected potential to exchange its coloration. Green or bluish-inexperienced in sunlight hours, alexandrite turns a tender colour of pink, purplish-red or raspberry red in incandescent mild. This specific optical characteristic makes it one of the maximum treasured gemstones of all, particularly in nice qualities.

Alexandrite is very scarce: this is due to its chemical composition. It is basically a chrysoberyl , a mineral consisting of colourless or yellow transparent chrysoberyl , chrysoberyl cat’s eye and colour-changing alexandrite (also in cat’s eye varieties). It differs from other chrysoberyl s in that it not only contains iron and titanium, but also chromium as a major impurity. And it is this very element which accounts for the spectacular colour change. Rarely, vanadium may also play a part. According to CIBJO nomenclature, only chrysoberyl s displaying a distinct change of colour may be termed alexandrite.

Like many other gemstones, alexandrite emerged millions of years ago in a metamorphic environment. But unlike many others, its formation required specific geological conditions. The chemical elements beryllium (a major constituent in chrysoberyl ) and chromium (the colouring agent in alexandrite) have contrasting chemical characteristics and do not as a rule occur together, usually being found in contrasting rock types. Not only has Nature brought these contrasting rock types into contact with each other, but a lack of the chemical element silica (the second most common element in the Earth's crust) is also required to prevent the growth of emerald. This geological scenario has occurred only rarely in the Earth's history and, as a result, alexandrite crystals are very scarce indeed.

Alexandrite mining

Russia has remained the number one source of alexandrite given that gemstones from the mines of the Urals became to be had available on the market. When the Russian deposits have been thought to have been exhausted, interest inside the precise shade miracle decreased - mainly considering that alexandrites from other mines not often displayed the coveted colour alternate. But the scenario modified dramatically in 1987, when alexandrites had been observed in an area referred to as Hematita in Minas Gerais, Brazil. The Brazilian alexandrites showed each a extraordinary color exchange and properly readability and coloration. Thus the really dulled image of the wonderful stone acquired some other raise. The colour of the Brazilian stones is absolutely now not as robust a green as that of Russian alexandrite, but the coloration exchange is clearly discernible. Today Hematita is one of the most critical deposits of alexandrite in financial terms. Occasionally alexandrite with chatoyancy is observed there, an effect which has not yet been located in Russian alexandrite. Alexandrites also are acquired from resources in Sri Lanka, but the hue of those stones compares much less than favourably with that of the Uralian alexandrites. They seem inexperienced in daytime and a brownish pink in synthetic light. The Tunduru area in southern Tanzania has also produced some extraordinary specimens for the reason that mid-1990s. Alexandrites are also located in India, Burma, Madagascar and Zimbabwe. Although this stone is still considered a rarity, specialised gemstone dealers do stock it, specially considering the fact that progressed change relationships among Russia and the rest of the sector have ensured a higher supply of Russian alexandrites to the marketplace.

Benitoite Gemstone

Benitoite is a rare blue barium titanium silicate mineral, found in hydrothermally altered serpentinite. Benitoite fluoresces under short wave ultraviolet light, appearing bright blue to bluish white in colour. The more rarely seen clear to white benitoite crystals fluoresce red under long-wave UV light.

California designated benitoite as the official state gemstone in 1985. Benitoite is sometimes called the "blue diamond." First discovered near the headwaters of the San Benito River in 1907 (hence the name), benitoite is a very rare gem that ranges in colour from a light transparent blue to dark, sapphire blue, or occasionally a violet shade.

Benitoite (pronounced "ben-ee-toe-ite") was initially thought to be a sapphire, but after careful analysis was found to be a mineral new to science. Gem quality benitoite cyrstals are found only in California.

Benitoite typically occurs with an unusual set of minerals, along with minerals that make up its host rock. Frequently associated minerals include: natrolite, neptunite, joaquinite, serpentine and albite.

Benitoite is a rare mineral found in very few locations including San Benito County, California, Japan and Arkansas. In the San Benito occurrence, it is found in natrolite veins within glaucophane schist within a serpentinite body. In Japan, the mineral occurs in a magnesio-riebeckite-quartz-phlogopite-albite dike cutting a serpentinite body.

Researchers at the Denver Museum of Nature & Science and University of British Columbia recently analyzed diamonds from the Museum's collection and learned how an unusual chunk of Africa formed.

It takes incredible heat and pressure to form a diamond. And when these diamonds were formed, microscopic minerals were trapped inside. The chemistry of these minerals, or inclusions, provides a rare look at the processes that led to the formation of Earth's crust. Inclusions found in the Museum's diamonds from the Congo craton in central southern Africa illustrate an incredible 3-billion-year journey through tectonic collisions and volcanic eruptions.

The international scientific team, led by author Charles W. Kosman, used an electron microprobe, an infrared spectrometer and a secondary ion mass spectrometer to analyze these diamonds.

"These diamonds are special," Kosman said. "They're the ultimate time capsules from deep Earth."

The researchers determined that the diamonds formed as thinner continental fragments and began their journey beneath the thick, buoyant continental crust of central Africa. Over 2.8 billion years, this part of the African continent repeatedly rammed into smaller and thinner fragments. These fragments slid downward back toward Earth's core where they were dehydrated by extreme heat and pressure, triggering the formation of diamonds. The diamonds were then brought to the surface in volatile eruptions, which pierced the hide of the ancient African continent and eventually deposited the diamonds on the surface.

"The circumstances that led to the formation of these diamonds trapping invaluable information inside are incredible," said James Hagadorn, Museum's curator of geology. "Grueling conditions -- temperatures five times hotter than your oven, and pressure 10 times that found below Mount Everest -- are what it takes to freeze clues to Earth's evolution for studies such as this one."

By knowing how and where diamonds like these are formed, it also informs the ability to predict where to find future diamond deposits. Museum collections are often overlooked as a resource for clues to Earth's delicate atmospheric history.

"Diamonds are a key part of our culture and industry. Not all diamonds end up on a ring or a saw-blade's edge. The ugly ones often have the coolest scientific stories to tell," said Hagadorn.

The name chrysoberyl comes from the Greek words chrysos, meaning golden, and beryllos, which refers to its beryllium content. Chrysoberyl has been a prized stone for thousands of years in Asia, as it is believed to provide the wearer with protection from the evil eye. There are three different gem varieties of chrysoberyl. Each of these stones is chemically alike, but optically very different, each one having a unique and beautiful feature of its own. The pale yellow green variety of chrysoberyl came from Brazil, and was known as chrysolite. It was popular in Spanish and Portugese jewelry in the 18th and 19th centuries. This stone displays an exceptional brilliance. Chrysoberyl is the third-hardest frequently encountered natural gemstone and lies at 8.5 on the hardness scale, between corundum and topaz.

Like the eye of a sleek feline predator, the chrysoberyl cat's eye winks at the astonished observer – a real miracle of Nature! That's why only this attractive gemstone has the right to the short, fitting name of "cat's eye". This gem is really something special with its narrow, bright band of light on a shimmering golden background, which seems to glide magically across the surface when the stone is moved.

Often, the name chrysoberyl is spoken in the same breath as that of the beryl group, the most well known representatives of which include the emerald and the aquamarine. The name 'chrysoberyl' comes from the Greek and means 'gold-coloured beryl'. In spite of its name, however, it is not actually a beryl at all. Together with alexandrite, chrysoberyl forms an independent gemstone category, in which the former, which appears to change its colour, is regarded as the more attractive representative, though in fact it is quite definitely the chrysoberyl cat's eye which is entitled to stake that claim.

From a mineralogical point of view, chrysoberyls are aluminium oxide containing beryllium, and thus actually have little in common with the beryls, which belong to the silicate family. Indeed, with their excellent hardness of 8.5 on the Mohs scale, they are clearly superior to the beryls. The popular chrysoberyls come in many nuances between lemon and greenish yellow, and in honey colours and shades from mint green to brownish green, and are mostly found in the gemstone deposits of Brazil, Sri Lanka or East Africa.

Popular Chrysoberyl

Alexandrite’s color change is caused by small amounts of iron or chromium. Alexandrite is also strongly pleochroic, appearing green, red, orange or yellow when viewed from different directions. Cat’s eye on the other hand, displays no pleochroism. The stone ranges in color from a honey yellow or honey brown color, to a yellowish green or almost emerald green. The most highly prized cat’s eye color however, is a light golden brown. Cat’s eye has a lovely velvety, silk like texture and is different than the common quartz variety of cat’s eye, which is brown and called tiger’s eye. Tiger’s eye is much weaker in color than cat’s eye.


Almandine, also known incorrectly as almandite, is a species of mineral belonging to the garnet group. The name is a corruption of alabandicus, which is the name applied by Pliny the Elder to a stone found or worked at Alabanda, a town in Caria in Asia Minor. Almandine is an iron alumina garnet, of deep red colour, inclining to purple. It is frequently cut with a convex face, or in cabochon, and is then known as carbuncle. Viewed through the spectroscope in a strong light, it generally shows three characteristic absorption bands.

It is also a popular gemstone and the maximum broadly used Garnet inside the gem trade. More gems are faceted from Almandine than some other kind of Garnet. Only a small amount of Almandine crystals are obvious and light enough for gemstone use; maximum of the Almandine observed is tough and opaque and no longer gem exceptional. Some Almandine Garnets show asterism while polished as cabochons, and are called "Star Garnets".


Almandine is frequently embedded in a mica schists, and forms very quality matrix portions with flawlessly formed symmetrical crystals. The schist matrix often breaks up due to weathering, ensuing in the Almandine crystals breaking free into character, flawlessly shaped floater crystals which can be pretty massive.

Almandine deposits

Almandine happens rather abundantly in the gem-gravels of Sri Lanka, whence it has occasionally been known as Ceylon-ruby. When the color inclines to a violet tint, the stone is often known as Syriam garnet, a name stated to be taken from Syriam, an historic metropolis of Pegu (now a part of Myanmar). Large deposits of great almandine-garnets had been determined, a few years in the past, in the Northern Territory of Australia, and were in the beginning taken for rubies and thus they had been regarded in change for some time afterwards as Australian rubies.

Almandine is broadly dispensed. Fine rhombic dodecahedra occur inside the schistose rocks of the Zillertal, in Tyrol, and are once in a while cut and polished. An almandine wherein the ferrous oxide is replaced partly by way of magnesia is determined at Luisenfeld in German East Africa. In the United States there are many localities which yield almandine. Fine crystals of almandine embedded in mica-schist occur near Wrangell in Alaska. The coarse kinds of almandine are often crushed to be used as an abrasive agent.

Types of Almandine Garnet consist of Carbuncle, Merelini Mint Garnet, Thai Garnet, Grandite, and Precious Garnet. Some uncommon Almandine crystals from India or Idaho have asbestos inclusions that create a exceptionally prized, megastar-like impact while faceted. Precious, or Noble Garnet, is deep red and obvious. Brown and opaque Almandine is ferrous and aluminum-like with lines of manganese and/or magnesium.

Healing homes of Almandine

In this text, the metaphysical residences of Almandine Garnet are explored. Almandine is a strong regenerative recovery crystal bringing electricity and stamina, and aids stream and all blood related problems.

It is an exceptional crystal for fertility, sexual potency and libido. Emotionally, Almandine cultivates a experience of safety, protection and abundance. It is related to the First Chakra and has the healing power to help arouse the kundalini and maintain the ones energies grounded.

It is a stone of physical love and relationships, and a non secular stone of psychic protection. It increases self-control and resistance to all things poor. Almandine Garnet degrees in color from light to deep scarlet, dark red, and muted sunglasses of brown.

A host of angels are associated with its shade energies and it honours three Goddesses. Garnet is the conventional birthstone of January, and Almandine is the natural birthstones of those born within the first month of autumn and mid-autumn.

Garnet is the zodiac stone for the ones born beneath the signal Aquarius, and is an Enhancer Strengthener crystal. It has the houses of fire power and is a talisman of protection.

Amazonite (sometimes called "Amazon stone") is a green variety of microcline feldspar. The name is taken from that of the Amazon River, from which certain green stones were formerly obtained, but it is doubtful whether green feldspar occurs in the Amazon area.

A green to blue-inexperienced sort of K-feldspar, usually microcline, but from time to time carried out to orthoclase. The coloration is usually caused by an improved content of Pb (up to one.2% PbO).

However, there are also symptoms that the green colour of a few microcline is caused by divalent Fe. Overenthusiastic uses of this call include giving this call to barely gray-inexperienced colorations in microcline that are regularly photosensitive and turn from greenish grey to light smoky gray. Sunlight can sometimes enhance the coloration of real amazonite.

Amazonite homes

Mohs Hardness of 6-6.5 with a triclinic crystal structure. Amazonite or Microcline is a form of alkali feldspar, and it’s colour is due to the presence of lead. Although the main colour of Amazonite is teal it may also be partially colourless, white, yellow, pink, red, gray or green. It’s striking colour is due to the presence of lead and is that mineral that determines the depth of the colour.


Amazonite is a mineral of limited occurrence. Formerly it was obtained almost exclusively from the area of Miass in the Ilmensky Mountains, 50 miles southwest of Chelyabinsk, Russia, where it occurs in granitic rocks. More recently, high-quality crystals have been obtained from Pike's Peak, Colorado, where it is found associated with smoky quartz, orthoclase, and albite in a coarse granite or pegmatite. Crystals of amazonite can also be found in Crystal Park, El Paso County, Colorado. Other locations in the United States which yield amazonite include the Morefield Mine in Amelia, Virginia. It is also found in pegmatite in Madagascar and in Brazil.

Because of its vivid green coloration when polished, amazonite is once in a while reduce and used as a reasonably-priced gemstone, even though it is without difficulty fractured, and loses its gloss because of its softness.

For many years, the source of amazonite's colour was a mystery. Naturally, many people assumed the colour was due to copper because copper compounds often have blue and green colours. More recent studies suggest that the blue-green colour results from small quantities of lead and water in the feldspar.

Amazonite recuperation residences

Amazonite assists in speaking one?S true thoughts and feelings with out over-emotionalism. It additionally permits one to see a problem from some other?S point of view for you to affect peace, or to see both facets of an trouble objectively to remedy one?S own inner conflicts. Sleeping with an Amazonite can convey these additives into recognition via the symbolism of goals.

As a guide stone, Amazonite aids in overcoming loneliness, and has been credited with making married lifestyles happier.

Amazonite is a Barrier Filter crystal that blocks geopathic stress, absorbs microwaves and cell smartphone emanations, and protects towards electromagnetic pollutants. Place it near computer systems and other electronics, or tape on your mobile cellphone.

In the place of work, Amazonite dispels negative energy and aggravation, and protects towards unfair commercial enterprise practices and others taking advantage. A stone of prosperity, Amazonite attracts new customers and orders to a business, and assists one in being within the proper area on the right time for brand new possibilities.

Amazonite is a superb good fortune stone for video games of chance, competitions and luck in any monetary project. To make a fortunate-attraction, combine three Amazonites and a small quantity of basil and mint in a small pouch. Leave it in front of a turquoise candle until the candle burns down.

Hide an Amazonite in a infant?S or teen?S bedroom to encourage tidiness, and maintain a dish of Amazonites on the kitchen table to influence others to assist more with chores.

Amber Gemstone

Amber is fossilised tree resin (not sap), which has been appreciated for its colour and natural beauty since Neolithic times. Much valued from antiquity to the present as a gemstone, amber is made into a variety of decorative objects. Amber is used as an ingredient in perfumes, as a healing agent in folk medicine, and as jewellery.

Amber is heterogeneous in composition, but consists of several resinous bodies more or less soluble in alcohol, ether and chloroform, associated with an insoluble bituminous substance. Amber is a macro-molecule by free radical polymerisation of several precursors in the labdane family, e.g. communic acid, cummunol, and biformene. These labdanes are diterpenes (C20H32) and trienes, equipping the organic skeleton with three alkene groups for polymerisation. As amber matures over the years, more polymerisation takes place as well as isomerization reactions, cross-linking and cyclization.

Molecular polymerisation, attributable to excessive pressures and temperatures produced with the aid of overlying sediment, transforms the resin first into copal. Sustained warmth and pressure drives off terpenes and consequences in the formation of amber.

For this to take place, the resin ought to be proof against decay. Many trees produce resin, but in the majority of instances this sediment is broken down by means of physical and biological techniques. Exposure to sunlight, rain, microorganisms (along with bacteria and fungi), and severe temperatures has a tendency to disintegrate resin. For resin to live on lengthy sufficient to grow to be amber, it must be immune to such forces or be produced beneath conditions that exclude them.

Amber is globally distributed, mainly in rocks of Cretaceous age or younger. Historically, the Samland coast west of Königsberg in Prussia was the world's leading source of amber. First mentions of amber deposits here date back to the 12th century. About 90% of the world's extractable amber is still located in that area, which became the Kaliningrad Oblast of Russia in 1946.

Pieces of amber torn from the seafloor are solid up by means of the waves, and collected by way of hand, dredging, or diving. Elsewhere, amber is mined, each in open works and underground galleries. Then nodules of blue earth must be eliminated and an opaque crust must be wiped clean off, which may be accomplished in revolving barrels containing sand and water. Erosion gets rid of this crust from sea-worn amber.

Caribbean amber, especially Dominican blue amber, is mined through bell pitting, that is risky due to the danger of tunnel fall apart.

The oldest amber recovered dates to the Upper Carboniferous period (320 million years ago). Its chemical composition makes it difficult to match the amber to its producers – it is most similar to the resins produced by flowering plants; however, there are no flowering plant fossils until the Cretaceous, and they were not common until the Upper Cretaceous. Amber becomes abundant long after the Carboniferous, in the Early Cretaceous, 150 million years ago, when it is found in association with insects. The oldest amber with arthropod inclusions comes from the Levant, from Lebanon and Jordan. This amber, roughly 125–135 million years old, is considered of high scientific value, providing evidence of some of the oldest sampled ecosystems.

In Lebanon more than 450 outcrops of Lower Cretaceous amber were discovered by Dany Azar a Lebanese paleontologist and entomologist. Among these outcrops 20 have yielded biological inclusions comprising the oldest representatives of several recent families of terrestrial arthropods. Even older, Jurassic amber has been found recently in Lebanon as well. Many remarkable insects and spiders were recently discovered in the amber of Jordan including the oldest zorapterans, clerid beetles, umenocoleid roaches, and achiliid planthoppers.

Baltic amber or succinite (historically documented as Prussian amber) is found as irregular nodules in marine glauconitic sand, known as blue earth, occurring in the Lower Oligocene strata of Sambia in Prussia (in historical sources also referred to as Glaesaria). After 1945 this territory around Königsberg was turned into Kaliningrad Oblast, Russia, where amber is now systematically mined.

It seems, but, to were in part derived from older Eocene deposits and it happens additionally as a derivative section in later formations, which include glacial drift. Relics of an abundant vegetation arise as inclusions trapped inside the amber at the same time as the resin become yet clean, suggesting family members with the plants of Eastern Asia and the southern a part of North America. Heinrich G?Ppert named the not unusual amber-yielding pine of the Baltic forests Pinites succiniter, but because the wood does no longer appear to vary from that of the prevailing genus it's been also referred to as Pinus succinifera. It is incredible, but, that the production of amber was restricted to a unmarried species; and certainly a huge number of conifers belonging to specific genera are represented in the amber-flora.

Amethyst Gemstone

Amethyst is a violet variety of quartz often used in jewellery. The name comes from the ancient Greek ἀ a- ("not") and μέθυστοςméthystos ("intoxicated"), a reference to the belief that the stone protected its owner from drunkenness. The ancient Greeks wore amethyst and made drinking vessels decorated with it in the belief that it would prevent intoxication. It is one of several forms of quartz. Amethyst is a semiprecious stone and is the traditional birthstone for February.

The shade in amethyst from most localities is inconsistently disbursed within the person crystals. In amethyst geodes it is frequently most intense in the boom zones beneath the rhombohedral faces (at the hints). Occasionally the shade is deeper under both the r or z rhombohedral faces, giving the crystal a pinwheel appearance when considered from the pinnacle. In prismatic crystals the coloration may additionally appear in phantom-like skinny layers, whilst in sceptres and skeleton quartz the coloration is often concentrated alongside the edges, and followed by way of smoky zones. Despite the acute coloration, the content material of iron occupying Si positions in amethyst is as an alternative low, within the 10-one hundred ppm variety.

When heated to extra than about 300-400?C, amethyst loses its violet shade and frequently turns yellow, orange or brown, after which resembles the quartz variety citrine, however relying on the locality and the temperature at some point of the heat treatment it may additionally turn colourless or not often green.

Irradiation with UV mild may also spoil the color centres, and for this reason extended exposure to sunlight will slowly fade amethyst. The image to the proper indicates the effects of warmth (backside left and proper) and UV irradiation (pinnacle right) at the colour of a specimen from Uruguay.

Amethyst is pleochroic whilst the polarisation of the mild is modified from parallel to the c-axis to perpendicular to the c-axis, amethyst modifications its coloration from blue-violet to pink. The electricity of the impact varies to a widespread degree, and modifications inside the hue depending at the direction of the transmitted light can be observable with the naked eye, in particular in crystals with a zonar improvement of color, which may also even show sky-blue tones.

Amethyst Crystals

Amethyst crystals do not get very large, crystals longer than 30 cm are very rare. It is discovered in numerous paperwork and shapes, the maximum not unusual growth paperwork are:

  1. Druzy crystal aggregates that outline cavities; the crystals are usually short-prismatic and often lack prism faces. Most common in volcanic rocks, but also in hydrothermal veins, and even in cavities in sedimentary rocks;
  2. Scepters (late syntaxial overgrowth) on other color varieties of quartz, in particular in high- to medium-temperature environments like alpine-type fissures and pegmatites
  3. Split-growth crystals ("artichoke quartz") in hydrothermal veins in ore deposits, but also in volcanic rocks.
  4. As individual well-formed crystals in small cavities and fissures, in particular in volcanic rocks.
  5. As hydrothermal vein filling, often with several growth phases with variable color that cause a banding pattern.


Amethyst is produced in abundance from the state of Minas Gerais in Brazil where it occurs in huge geodes within volcanic rocks. Many of the hollow agates of southwestern Brazil and Uruguay comprise a crop of amethyst crystals inside the interior. Artigas, Uruguay and neighbouring Brazilian state Rio Grande do Sul are massive global producers exceeding in amount Minas Gerais, in addition to Mato Grosso, Espirito Santo, Bahia, and Cear? States, all amethyst producers of significance in Brazil.

It is also determined and mined in South Korea. The largest opencast amethyst vein in the world is in Maissau, Lower Austria. Much best amethyst comes from Russia, specifically from close to Mursinka inside the Ekaterinburg district, where it occurs in drusy cavities in granitic rocks. Many localities in south India yield amethyst. One of the most important worldwide amethyst manufacturers is Zambia in southern Africa with an annual production of approximately 1000 tonnes.

Amethyst occurs at many localities in the United States. Among these may be mentioned: the Mazatzal Mountain region in Gila and Maricopa Counties, Arizona; Red Feather Lakes, near Ft Collins, Colorado; Amethyst Mountain, Texas; Yellowstone National Park; Delaware County, Pennsylvania; Haywood County, North Carolina; Deer Hill and Stow, Maine and in the Lake Superior region of Minnesota, Wisconsin and Michigan. Amethyst is relatively common in the Canadian provinces of Ontario and Nova Scotia. The largest amethyst mine in North America is located in Thunder Bay, Ontario.

Amethyst types

Purple Amethyst

Purple Amethyst has been highly esteemed throughout the ages for its stunning beauty and legendary powers to stimulate, and soothe, the mind and emotions. It is a semi-precious stone in today’s classifications, but to the ancients it was a “Gem of Fire,” a Precious Stone worth, at times in history, as much as a Diamond. It has always been associated with February, the month the Romans dedicated to Neptune, their water-god, and is the traditional birthstone of that month. It is the stone of St. Valentine and faithful love, and signifies ecclesiastical dignity as the Bishop’s Stone. It carries the energy of fire and passion, creativity and spirituality, yet bears the logic of temperance and sobriety.

Brandberg Amethyst

Brandberg Amethyst is a unique and extraordinary blend of Amethyst, Clear and Smoky Quartz together in one exceedingly high-vibrational crystal. It is found only in Namibia, Africa, and is imbued with remarkable phantoms, enhydros, and other rare formations and inclusions. It attunes to pure consciousness and is a potent talisman of healing and perfection with the capacity to restore one back to their etheric blueprint in order to realign with the Divine Source.

Chevron Amethyst

Chevron Amethyst displays v-shaped chevrons of deep purple and white Quartz that “seep” into beautiful layers. It is one of the finest Third-Eye stones for stimulating vision within the self as well as the physical world, filtering the life force from the cosmos via the Crown in its white layers and opening up spiritual and psychic channels through the purple. It has a strong, focused energy for dissipating and repelling negativity, and is the perfect crystal for learning any form of spiritual healing. Hold one in each hand for powerful but safe out-of-body travel, shamanic journeying or pathworking, and between the hands while praying or reciting mantras.

Cacoxenite in Amethyst

Cacoxenite in Amethyst mingles dark brown to yellow tufts of Cacoxenite, a phosphate mineral and major component in the Super Seven crystal, with the host crystal Amethyst. This combination brings a high level of creativity and new ideas to humanity by fostering thoughts that have never been thought of before. It is a calming stone, good in times of upheaval, and raises spiritual awareness of the creator essence in the beauty of nature and the kindness in people. Carry on the night of the crescent and full moon to transfer healing energy to the Earth and create an ethereal connection between all of the universe.

Rutiliated Amethyst

“Rutilated” Amethyst is a rare form of Amethyst which appears to contain Rutile, but actually contains brownish crystals of Goethite, an iron hydroxide mineral also found in the Super Seven crystal.

A glassy, translucent stone, Carnelian is an orange-coloured variety of Chalcedony , a mineral of the Quartz family. Its colour varies from pale pinkish-orange to a deep rusty brown, though it is most known for its brilliant orange and red-orange crystals. Its name comes from a Latin word meaning "flesh."Carnelian (also spelled cornelian) is a brownish-red mineral which is commonly used as a semi-precious gemstone. Similar to carnelian is sard, which is generally harder and darker (the difference is not rigidly defined, and the two names are often used interchangeably). Both carnelian and sard are varieties of the silica mineral chalcedony coloured by impurities of iron oxide. The colour can vary greatly, ranging from pale orange to an intense almost-black coloration. It is most common in Brazil, India, Siberia and Germany.

The bow drill was used to drill holes into carnelian in Mehrgarh between 4th-5th millennium BC.Carnelian was recovered from Bronze Age Minoan layers at Knossos on Crete in a form that demonstrated its use in decorative arts; this use dates to approximately 1800 BC. Carnelian was used widely during Roman times to make engraved gems for signet or seal rings for imprinting a seal with wax on correspondence or other important documents. Hot wax does not stick to carnelian. Sard was used for Assyrian cylinder seals, Egyptian and Phoenician scarabs, and early Greek and Etruscan gems. The Hebrew odem (translated sardius), the first stone in the High Priest's breastplate, was a red stone, probably sard but perhaps red jasper.

Although now the more common term, "carnelian" is a 16th-century corruption of the 14th-century word "cornelian" (and its associated orthographies corneline and cornalyn). Cornelian, cognate with similar words in several Romance languages, comes from the Mediaeval Latin corneolus, itself derived from the Latin word cornum, the cornel cherry, whose translucent red fruits resemble the stone. The Oxford English Dictionary calls "carnelian" a perversion of "cornelian", by subsequent analogy with the Latin word caro, carnis, flesh. According to Pliny the Elder, sard derives its name from the city of Sardis in Lydia, but it more likely comes from the Persian word سرد sered, meaning yellowish red.

Orange stones, especially the carnelians, are excellent aids for training, coordination of physical exercise programs, and for balancing body energy levels. Carnelians boost a listless attitude and can stimulate the appetite.

Used as a professional support crystal, Carnelian aids architects, builders and construction workers in their creation of master buildings, stimulates power and stamina in athletes and military personnel, establishes form and organisation in journalists, and stimulates motivation in salespersons.

Carnelian is said to attract prosperity, new resources and good luck. It is a talisman for success in any money-making venture. In the workplace, it is a crystal of ambition, drive and determination, and wards off undue pressures of co-workers or impersonal corporations with unrealistic expectations.

Carnelian clarifies the voice. It is the Singer's Stone. It also promotes confidence for performances on stage or in live media.

Carnelian is traditionally known to guard against falling masonry and accidents with tools. Today it guards the home from theft, fire, storm or accident.

Carnelian lends the courage needed to help overcome difficulties and defend a cause. It promotes idealism, a sense of community and pragmatism.

Orange and red Carnelian are important crystals to use for love, and for the consummation of love. Orange crystals, in particular, are fertility and potency symbols and are linked with conceiving a child. Carnelian of either color may help in rekindling passions that might have faded in an otherwise loving relationship

Chalcedony is a cryptocrystalline form of silica, composed of very fine intergrowths of quartz and moganite. These are both silica minerals, but they differ in that quartz has a trigonal crystal structure, while moganite is monoclinic. Chalcedony's standard chemical structure (based on the chemical structure of quartz) is SiO2 (silicon dioxide).

Chalcedony has a waxy luster, and can be semitransparent or translucent. It can assume a huge variety of colors, however the ones maximum generally seen are white to gray, grayish-blue or a shade of brown ranging from pale to almost black. The color of chalcedony bought commercially is frequently enhanced by means of dyeing or heating.

The name chalcedony comes from the Latin chalcedonius (alternatively spelled calchedonius). The name appears in Pliny the Elder's Naturalis Historia as a term for a translucid kind of Jaspis. The name is probably derived from the town Chalcedon in Asia Minor.. It is a hapax legomenon (the term for a word found nowhere else) so it is hard to tell whether the precious gem mentioned in the Bible is the same mineral known by this name today.


Fine examples of first century objects made from chalcedony, possibly Kushan, were found in recent years at Tillya-tepe in north-western Afghanistan. Hot wax would not stick to it so it was often used to make seal impressions. The term chalcedony is derived from the name of the ancient Greek town Chalkedon in Asia Minor, in modern English usually spelled Chalcedon, today the Kadıköy district of Istanbul.

In the 19th century Idar-Oberstein, Germany became the world's largest chalcedony processing centre, in particular agates. Most of these agates were from Latin America, in particular Brazil. Originally the agate carving industry around Idar and Oberstein was driven by local deposits that were mined in the 15th century. Several factors contributed to the re-emergence of Idar-Oberstein as agate centre of the world: ships brought agate nodules back as ballast, thus providing extremely cheap transport. Also, cheap labour and a superior knowledge of chemistry allowing them to dye the agates in any colour with processes that were kept secret helped. Each mill in Idar Oberstein had four or five grindstones. These were of red sandstone, obtained from Zweibrücken; and two men ordinarily worked together at the same stone.



Chalcedony was once thought to be a fibrous variety of cryptocrystalline quartz. More recently however, it has been shown to also contain a monoclinic polymorph of quartz, known as moganite. The fraction, by mass, of moganite within a typical chalcedony sample may vary from less than 5% to over 20%. The existence of moganite was once regarded as dubious, but it is now officially recognised by the International Mineralogical Association.


Chalcedony is more soluble than quartz under low-temperature conditions, regardless of the two minerals being chemically equal. This is concept to be due to the fact chalcedony is extraordinarily finely grained (cryptocrystalline), and so has a completely excessive surface place to quantity ratio. It has additionally been suggested that the higher solubility is because of the moganite thing.

Blue Chalcedony is an extraordinary crystal for public speakers and those who talk for a living. Lawyers and political audio system may advantage from touching this stone to the end in their tongue at the same time as taking note of their opponents to enhance their counter arguments.

Actors may rub it in opposition to their lips and throat, at the same time as singers can also drink a pitcher of water in which Chalcedony has soaked for an hour before going on stage. Wearing this crystal around the neck allows triumph over level fright and the worry of public speakme.

As a stone of peace and peace-making, Blue Chalcedony encourages stillness and calm in the domestic for the ones at odds with each other, vying for their region in the pecking order. It is likewise useful for each day journeys to paintings, or traumatic journeys concerning youngsters.
