Very rare mineral of the Borate Class.
Jeremejevite is quite hard and well suitable for jewellery use. However, due to its extreme rarity, it is hardly ever encountered in the gem trade.

Ameib Farm, Erongo,Namibia

Origin of name: firstly described in 1883 by French mineralogist Augustin Alexis Damour, who named it in honour of Russian mineralogist, crystallographer and engineer Pawel Wladimirowich Jeremejew (1830–1899). (Source:

Synonyms and trade names: none, but there do exist different spellings like
Jeremejewite or Yeremeyevite

Can be confused with: Jeremejevite can be colourless, yellowish and light blue to slightly purplish blue and thus can be confused with almost all other gems of similar colour. Identification is achieved by measuring physical properties e.g. refractive index.

Localities: firstly found at Mt. Soktuj (Soktuj Gora) in Russia, which is the type locality. However, this locality only yielded tiny crystals, not suitable for cutting.
There are only about a dozen known localities worldwide, six of them in Germany (Eifel) alone. Unfortunately the German sources also only produce tiny, unfacettable crystals.
The most important sources are all located in the Erongo Region in Namibia. Besides a small deposit near the town of Swakopmund it was the so-called 72 Mile deposit (72 miles north of Swakopmund on the coastal road), where the first really good Jeremejevites were found in the early 1970ies.
Since 2006 a farm called Ameib, near Usakos, occassionally yields good crystals, from which gems of fine colour and impressive size (in the case of Jeremejevite this means above 1ct) have been cut.

Three Jeremejevites from Ameib Farm, Erongo, Namibia

Other sources are the Pantahole Mine near Momeik, Myanmar (Burma) and a deposit near the Tadjik town of Chorugh (Khorog).

Handling: Jeremejevite is quite hard, not brittle, has no cleavage and thus should be well suitable for use in jewellery. However, it is so rare that we have no empirical data from goldsmiths or setters.
According to our cutters, Jeremejevite can be cut and polished without any problems and shows no reaction to heat. It must be said, though, that the temperatures reached when dopping the stone do not exceed 60°C.
We also do not know, whether it is susceptible to acids and brines.

Because of the rarity it is almost impossible to replace Jeremejevite in case of damage. Thus we would serioulsy advise you to take it out of the setting prior to any repair jobs. We would also advise you to keep it away from acids, brines and galvanic baths and not to clean it ultrasonically.

A request to goldsmiths and setters: if you have any experience with Jeremejevite please let us know – thank You.

Worth knowing: Jeremejevite is piezoelectric.

Ironstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron compound from which iron either can be or once was smelted commercially. This term is customarily restricted to hard coarsely banded, nonbanded, and noncherty sedimentary rocks of post-Precambrian age. The Precambrian deposits, which have a different origin, are generally known as banded iron formations. The iron minerals comprising ironstones can consist either of oxides, i.e. limonitehematite, and magnetite; carbonates, i.e. siderite; silicates, i.e. chamosite; or some combination of these minerals.


Freshly cleaved ironstone is usually grey. The brown external appearance is due to oxidation of its surface. Ironstone, being a sedimentary rock is not always homogeneous, and can be found in a red and black banded form called tiger iron, sometimes used for jewelry purposes.Sometimes ironstone hosts concretions or opal gems.


Ironstone occurs in a variety of forms. The various forms of ironstone include siderite nodules; deeply weathered saprolite, i.e. (laterite); and ooidal ironstone .

Ironstone as a source of iron

Ironstone, although widespread, is a limited source of iron (Fe). Historically, most of British iron originated from ironstone, but it is now rarely used for this purpose because it is far too limited in quantity to be an economic source of iron ore.


Ironstone’s oxide impurities render it useless as a component in ceramics: the “ironstone china” of Staffordshire and American manufacture, a fine white high-fired vitreous semi-porcelain, commonly used for heavy-duty dinner services in the 19th century, depends on the whiteness of its body. Its “iron” quality is in its resistance to chipping, not in any ingredient in its manufacture.

In construction

The stone can be used as a building material. Examples include the parish churches at Kirby Bellars and South Croxton in Leicestershire.

Enclosing a fascinating past in itself, iolite is an amazing stone, which was once used by the mariners as the compass to guide their way through the sea. With shifting shades of blue and violet, iolite carries the spirit of dreams, imagination, journey, and exploration. It is also referred as the Vikings compass because other than just practically being used as a compass, Iolite provides the person to move spiritually and physically from one area to another.Iolite also includes in itself a unique property, which is known as pleochroism. Pleochroism is a phenomenon with which one can see a kaleidoscopic effect when the stone is seen through in different positions. Iolite is also called as the “Water Sapphire”, and has derived its name from “ios”, which means violet.

Howlite Gemstone Information

Howlite Gemstone Information

About Howlite – History and Introduction

Howlite was named after Henry How, who discovered it in 1868 in Nova Scotia. Henry How was a Canadian chemist, geologist and mineralogist who was told of this previously unknown mineral by gypsum quarry miners who found it hampered their mining because it is harder than gypsum. Howlite is a borate mineral, which occurs in Canada and parts of the USA. It forms as irregular nodules which can appear in the shape of a cauliflower head. Transparent howlite crystals are extremely rare and are small (the largest documented howlite crystals are 1 cm long), but the nodules can occur in masses of over 50 kilograms. Howlite has the appearance of white marble or porcelain with a sub-vitreous luster. It is opaque and white or grey with grey, black or dark brown veins running through it. Gemstone quality howlite can be interspersed by the darker matrix (which appears as the veins), or it can be matrix-free and pure white. Howlite is best known for imitating other gemstones. Due to its porous nature, howlite can absorb dye well, which means it can be sold as turquoise, red coral, or lapis lazuli. However, honest gem traders always declare any treatments.

Howlite Gemstone

Howlite is quite porous and because of this quality, it can be dyed to imitate similar colored stones such as turquoise, coral and lapis lazuli. However, howlite itself is generally not mimicked. Howlite is sometimes misleadingly sold as “white turquoise”, or also called “the sacred buffalo stone” or “the white buffalo stone”. Howlite has a similar appearance and hardness to white marble, but white marble has a low porosity compared to the porous howlite.

Although howlite was discovered in Canada, most howlite now comes from California and Los Angeles, USA. Deposits have also been found in Turkey, Germany, Mexico and Russia. Rare transparent howlite crystals have only been found in two places; Tick Canyon, California and Iona, Nova Scotia.

Howlite Color

Howlite is milky white or grey, and is interspersed with black or dark brown veins. These veins are the matrix, or surrounding stone. It can also be pure white, which means that the matrix (surrounding stone) is not present in the gemstone.

Howlite Clarity and Luster

It is opaque with a sub-vitreous (glimmering) luster. Howlite also occurs in transparent crystal form, but this is extremely rare.

Howlite Cut and Shape

Howlite has indistinct cleavage, which means that it is not suitable for faceting. Howlite can be cut en cabochon, fashioned into spheres, egg shapes, ovals, pear shapes or fancy shapes, including skulls. It can also be tumbled and drilled to make beautiful beads. Howlite is an attractive ornamental stone and is often cut into globes or carved into fancy shapes, such as animal ornaments.

Howlite Treatment

Howlite is quite porous, so it is often dyed to imitate other minerals, especially turquoise. However, howlite is softer than turquoise. Due to howlite’s distinctive veining, when dyed blue, it can be passed off as turquoise. This may have caused howlite to be misleadingly known as “white turquoise”, “white buffalo turquoise” or “white buffalo stone”. Dyed howlite is also sold as “turquenite”. Howlite has also been dyed deep blue to simulate lapis lazuli, or red to imitate coral. Dyed howlite is sometimes coated with a resin to seal (and conceal) the dye and make the gemstone harder. Honest gem traders always declare any

As mentioned above, howlite can be dyed to look like other minerals, such as turquoiselapis lazuli or coral.

Howlite is said to balance calcium levels and strengthen the bones and teeth. It is also thought to be a calming stone that can relieve insomnia, therefore, some insomniacs place a piece of howlite beneath their pillow to encourage restful sleep. In traditional Hindu belief systems, howlite is considered to benefit the third eye chakra, and when placed on this chakra, between the brows, it is thought to open up memories of previous lives. Howlite is a non-traditional stone for those born under the zodiacal sign of Gemini. Additionally, howlite is believed to eliminate anger and absorb negative energy.

Howlite is quite a soft substance when compared to other gemstones, but its lack of cleavage means that it is quite versatile. Howlite gems make distinctive bolo ties, also known as “bootlace ties”. Spherical drilled howlite stones make attractive beaded necklaces and bracelets. Smooth tumble-finished howlite stones are also drilled and used to make necklaces and bracelets. Additionally, fancy cut or cabochon cut howlite stones make unique pendants.

Note: Buy colored gemstones by size and not by carat weight. Colored stones vary in size-to-weight ratio. Some stones are larger and others are smaller than diamonds by weight in comparison.

Howlite is most famous, or rather, infamous for imitating other gems, and does not yet seem to be fully appreciated in its own right. Therefore, there are no world famous howlite gemstones, to date.

How to clean your gemstonesHowlite is softer than many other gems, so it can be easily scratched. Since howlite dissolves in hydrochloric acid, harsh household chemical cleaners should be avoided. Howlite is softer than common quartz, and since ordinary dust often contains traces of quartz, simply wiping off dust can eventually lead to reduced polish and unwanted surface scratches. To clean your howlite, simply use soapy water and a soft cloth. Be sure to rinse well to remove soapy residue. As with most gemstones, ultrasonic cleaners and steamers are not recommended. Always remove any jewelry or gemstones before exercising, cleaning or engaging in harsh physical activities such as sports. Store howlite away from other gemstones to avoid scratches. It is best to wrap gemstones in soft cloth or place them inside a fabric-lined jewelry box.

Hiddenite Gemstone Information

Hiddenite Gemstone Information

About Hiddenite – History and Introduction

Hiddenite was named after W.E. Hidden, who discovered it in 1879 in North Carolina. Hidden travelled to North Carolina to find platinum for Thomas Edison’s electric light bulb. Hidden leased Warren Farm to mine emeralds, and found hiddenite. Hiddenite is a green type of spodumene. Spodumene is green, pinkish or lilac and is used as a source of lithium. Hiddenite can appear green-yellow, yellow-green or a striking emerald-green. In fact, hiddenite was also referred to as the “lithia emerald” when mining of it reached its peak in the 1800s. This is because of its vivid green color. In fact, hiddenite was described in a newspaper in 1892, by Kunz, as being having a “peculiar brilliancy which is wanting in true emerald”. Hiddenite is popular with collectors and museums.

Hiddenite Gemstone

Hiddenite’s pleochroism can help to distinguish it from other gems. A combination of this, its perfect cleavage, hardness, monoclinic crystal system, transparency and color can distinguish hiddenite from other gems.

The mining area of North Carolina, USA, where hiddenite was discovered, has been named Hiddenite, after the gem. The Emerald Hollow Mine in Hiddenite is open to the public. Deposits of hiddenite have also been found in Afghanistan, Myanmar (Burma), Brazil, Madagascar and California.

Hiddenite Color

Hiddenite is colored by chromium; the chromium oxide gives it a green color. This is why some of it appears bottle green, since chromium oxide is added to glass to create green glass bottles. Hiddenite varies in color from an almost imperceptible and almost clear light-green to yellow-green and at its darkest, deep bottle (emerald) green. It is yellow-green, green-yellow or emerald-green in color. Hiddenite is pleochroic, which means that it displays different colors when seen at different angles. Therefore, a single piece of hiddenite can appear to be blue-green, emerald green or yellow-green. The most valuable hiddenite is an intense emerald green.

Hiddenite Clarity and Luster

Hiddenite is transparent with a vitreous (glassy) luster. Good quality hiddenite gemstones are usually eye-clean with no visible inclusions.

Hiddenite Cut and Shape

Hiddenite has perfect cleavage, which means that it is difficult to cut. It needs to be carefully cut, so that it is less vulnerable to breakage. It is usually emerald cut (also known as step cut), though some lapidarists will cut it en cabochon rather than risk damaging the stone. Also, settings should be considered. Gems with perfect cleavage are usually mounted in protective settings or set in earrings or pendants that are not likely to be struck by force. It forms as monoclinic crystals; in the shape of tabular prisms. Due to hiddenite’s cleavage, splintery fracture and strong pleochroism, it is considered a real gem cutter’s challenge. Hiddenite gemstones that are expertly faceted are quite rare, so they are also very valuable.

Hiddenite Treatment

Hiddenite is not usually exposed to treatment, however, lighter spodumene specimens can be treated by irradiation to bring about an emerald-green hue.

Chemical Formula: LiAlSi2O6, Lithium aluminum silicate
Crystal Structure: Monoclinic, prismatic and tabular
Color: Yellow-green, green-yellow and emerald-green

Cleavage: Perfect
Transparency: Transparent
Double Refraction or Birefringence: 0.014 to 0.016
luster: Vitreous
Fluorescence: Very weak; red-yellow

Please refer to our Gemstone Glossary for details of gemology-related terms.

Emerald Gems
Emerald Gem

Hiddenite can be confused with chrysoberyl (which is different because it has an orthorhombic crystal habit), diopside, emerald, peridot, precious beryl and verdelite. Emeralds are often found alongside hiddenite, but emerald can be identified by its indistinct cleavage, inclusions, hexagonal crystal system and hardness.

Hiddenite is a non-traditional birthstone for those born in August and a non-traditional zodiacal stone for Librans. Hiddenite is said to help its wearer to get in touch with their emotions by liberating them from fear and encouraging compassion and loving kindness. The healing properties of hiddenite are thought to help heal the heart and provide comfort from emotional stress. In traditional Hindu belief systems, hiddenite is thought to be of benefit to the brow, or “third eye” chakra, which is the eye of intuition and the intellect.

Hiddenite is ideal for rings, necklaces, bracelets and pendants. It can be fashioned into almost any shape. Hiddenite makes attractive faceted gemstones, cabochons or sperical beads. As with diamond, hiddenite should be protected from hard knocks by protected settings in rings for daily wear. This is because a single blow could cause fracturing due to perfect cleavage. Hiddenite is hard (6.5 – 7 on the Mohs scale), which gives it durability and resistance to scratches.

Note: Buy colored gemstones by size and not by carat weight. Colored stones vary in size-to-weight ratio. Some stones are larger and others are smaller than diamonds by weight in comparison.

There are not any world-famous hiddenite gems to date. However, there is a 365 carat hiddenite gem on display as part of a collection in the UK.

How to clean your gemstonesHiddenite is a rare gem, so it is not usually seen as jewelry. Due to its perfect cleavage, hiddenite would be best set in protective settings such as bezel settings, which would help to prevent damage caused by a sudden blow. Mostly, hiddenite is faceted only for gemstone and mineral collectors’ displays and showcases. Although it is considered hard enough to endure wearing in ‘protected’ jewelry designs, such as earrings, pendants, pins or brooches, daily wear as rings or bracelets is not recommended as it can easily fracture and chip because of its perfect cleavage. To clean your hiddenite, simply use soapy water and a soft cloth. Be sure to rinse well to remove soapy residue. As with most gemstones, ultrasonic cleaners and steamers are not recommended. Always remove any jewelry or gemstones before exercising, cleaning or engaging in harsh physical activities such as sports. Store hiddenite away from other gemstones to avoid scratches. It is best to wrap gemstones in soft cloth or place them inside a fabric-lined jewelry box.

Metaphysical Properties

Hematite is the mineral form of iron oxide, which is one amongst the several iron oxides. The crystallization of Hematite takes place in the rhombohedral lattice system and it possesses the same crystalline attributes as those of limonite and corundum.

Hematite is one of the most general minerals. Hematite is responsible for the coloration of most of the red and brown rocks, such as sandstone. Not only this, Hematite is also responsible for the red color of many other gemstones such as spinal, ruby and garnet to some extent. Traces of Hematite can be found in these stones. Hematite is much solid than pure iron, but at the same time fragile as well. On Moh’s scale the hardness of the Hematite ranges in between 5.5 to 6.5.

The earthy forms of Hematite are generally dull or metallic in their lustre.

Hematite Color

Hematite is generally black in color with speckles of gold and other colors in which it is found are grey, reddish brown, brown, and red.

Hackmanite Gemstone Information

Hackmanite Gemstone Information

About Hackmanite – History and Introduction

Hackmanite is an exceptionally rare sulfur-rich variety of sodalite which exhibits tenebrescence (the ability of minerals to change color when exposed to sunlight). It was first discovered in Greenland in 1896 by L. C. Boergstroem, and was later named after Victor Axel Hackman (1866-1941), a Finnish geologist. However, it wasn’t until recently (1991) that the first gem-quality hackmanite deposit was discovered in Quebec, Canada.

Hackmanite appears pale to deep violet when first mined, but once exposed to sunlight, the color quickly fades to grayish or greenish-white. When placed back into a dark place or when exposed to short wave ultraviolet light, the violet color slowly returns. The change in color can be seen within seconds of being exposed to sunlight, but the return of the original color can sometimes take up to a week. The tenebrescence effect can be repeated indefinitely, but is detroyed by heating.

The tenebrescence effect seen in hackmanite is the rarest of all gemstone optical phenomena. It is often confused with the ‘color change‘ phenomenon, where materials can shift color under different types of light sources. Another term for tenebrescence is ‘reversible photochromism’. A common example of reversible photochromism can be seen in everyday color-change eyeglass lenses. Color-change eyeglasses darken when exposed to sunlight and lighten up again when they are brought indoors. The effect is caused by a photochemical reaction to UV radiation and is known to occur in only a few rare materials.

Hackmanite Gemstones

Hackmanite is member of the feldspathoid group of minerals. The feldspathoids are a group of tectosilicates which closely resemble feldspars but exhibit a slightly different structure and lower silica composition. Hackmanite is sulfur-rich chloric sodium aluminum silicate with a hardness of 5.50 to 6.00 on the Mohs scale. It has a low density or specific gravity of 2.14 to 2.40, making it one of the least dense of all gemstones (slightly denser than opal). Most hackmanite is opaque, but high quality specimens can occur transparent to translucent in form. Hackmanite can be easily identified and distinguished from its parent stone ‘sodalite’ by the presence of sulfur and color change tenebrescence.

Hackmanite was first discovered in Greenland, but it can also be found in a few other locations, including Afghanistan, Myanmar (Burma) and Quebec, Canada.

Striking purple hackmanite originating from the lazurite mines of Sar-e Sang, Koksha Valley of Badakshan Province in Afghanistan are considered the most desirable of hackmanite stones, which are highly sought after by gem and mineral collectors.

Hackmanite Color

Hackmanite appears pale to deep violet when first mined, but quickly fades to grayish or greenish white once exposed to sunlight. However, hackmanite from Afghanistan and Myanmar does the opposite and tends to change color from colorless or creamy white to pink-red or violet under sunlight. The most desirable specimens are those that change from colorless or a very light color to an intense deep purple.

Hackmanite Clarity and Luster

Most hackmanite is opaque, but fine quality crystals can occur transparent to translucent. Inclusions are common, typically as white streaks or veins composed of calcite. Hackmanite exhibits a vitreous luster when cut and polished; on fractures, luster can appear greasy.

Hackmanite Cut and Shape

Hackmanite is often faceted for collectors or display only. In most cases, hackmanite is cut and sold in slices or slabs. The most common faceted shapes include ovals and other shapes which maximize the rough carat weight. Opaque materials may be shaped into cabochons.

Hackmanite Treatment

Hackmanite is not treated or enhanced in any way. Heating of hackmanite can result in the permanent loss of tenebrescent ability.

Sodalite Gemstones

Hackmanite is a sulfur-rich variety of sodalite. Sodalite is mostly known for its blue color, but it can actually occur colorless, gray, yellow, green, violet, blue to deep blue and pink. There are no other gemstone varieties closely-related to hackmanite and sodalite, although they both share mineralogical similarities with many of the feldspar varieties.

Other gemstones that can be easily confused with sodalite and hackmanite include many popular gemstones, such as blue lapis lazuliblue azurite, blue lazulite and blue dumortierite quartz.

Hackmanite is known as the ‘stone of eternal belonging’. It is a stone which is said to remind us of how everything has its own time and place. Hackmanite encourages its wearer to recognize that all things have belonging. Hackmanite is thought to be helpful for those who suffer from harassment, fear and apprehension. It is believed to stimulate audacity and strengthen self-esteem, while encouraging feelings of happiness, confidence and contentment.

Hackmanite is sometimes referred to as the chameleon stone, and depending on the actual color state of the stone, it is thought to provide different metaphysical abilities and healing powers. Although it is not an official birthstone for any month, hackmanite is associated with the astrological sign of Sagittarius. It is believed to be an excellent stone for the throat, third eye and heart chakra.

Hackmanite is exceptionally rare. It is considered a collector’s stone and is not recommended for jewelry wear. It is relatively soft, but with its indistinct cleavage, it’s actually quite durable. For those seeking incredibly rare jewelry, hackmanite could be worn with care as a pendant or brooch. On the other hand, sodalite, the more common blue sister stone of hackmanite, is quite often used for cabochon and beaded jewelry. It is also very popular for use in the making of arts and crafts as well as ornamental gemstone carvings.

Note: Buy colored gemstones by size and not by carat weight. Colored stones vary in size-to-weight ratio. Some stones are larger and others are smaller than diamond by weight in comparison.

How to clean your gemstonesHackmanite is fairly soft compared to most other gemstones, so it may require some special care. You can clean hackmanite stones using warm water and a mild soap or detergent if needed. Be sure to rinse well to remove any soapy reside. Do not use any harsh chemicals or cleaners and avoid extreme heat. Heating hackmanite can result in the permanent loss of its desirable tenebrescent effect.

Always remove any hackmanite jewelry when participating in any strenuous physical activity, such as playing sports, doing household chores or exercising. When storing hackmanite, always store it separately and away from other gems and jewelry. If possible, it is best to wrap it in a soft cloth or place it inside a fabric-lined jewelry box.
