Achroite Tourmaline

Achroite Tourmaline: Colorless Tourmaline, also known as white or Achroite Tourmaline is the name given to the clear or colorless version of Tourmaline. The word achroite is Greek for colorless. If you are into birthstones then Achroite Tourmaline is one of the ones used for October. If you follow the zodiac then it's used to represent Libra. Tourmaline in general is found on every continent and is possibly the (read full)

Barite

Barite: Barite also called Baryte or heavy spar is a clear to yellowish to blue mineral that is very soft and not well suited for making of gemstones. (Its a 3 on the harness scale). Its found near lead-zinc mines within limestone deposits. All in all a nice item for a collector, but in terms of long term jewelry this is not a very suitable gem for rings, and necklaces as it will break and shear apart wh (read full)

Beryllonite

Beryllonite: Beryllonite is a clear gem/mineral that gets its name from its high content of beryllium. There are very few gem quality pieces that have been produced. Beryllonite can be found in Pakistan, Brazil, Finland, and Maine. It has a color streak of white, and a vitreous luster. (read full)

Anglesite

Anglesite: Anglesite is a very soft gem just slightly harder than gold and silver and as such it does not hold facets well/cut easily. Because of its softness it tends to scratch, and these scratches will take away from the value and appearance of this gem. Once cut this gem will not do well in rings as it will quickly become scratched and its edges worn round. This gem is usually colorless or clear, but (read full)

Amblygonite

Amblygonite: Amblygonite is a not so popular gem whose greek name means crooked. It comes in green, clear, yellow, and even purple. Older cut specimens may have slightly rounded facet edges due to the gems lack hardness (6 of 10). Amblygonite can be found in Brazil, France, the United States, Burma, and even Sweden. It may be confused easily with Brazilianite. (read full)

Aragonite

Some of the better specimens have been found in upper North America including the United States and Canada In 1815 Albite was given the Latin name albus which literally means white. Albite astrological sign is that of A (read full)

Benitoite

Benitoite: Benitoite is a rare gemstone / mineral that fluoresces when lit by black lights. It gets its name from San Benito County, California where it was first found. This gem is almost always blue (it was originally thought to be a sapphire) but also has variations in purple, pink, and clear. Gem prices seem to fluctuate but a few hundred dollars per half ct is common. Why so expensive? The quality gem (read full)

Aventurine

Aventurine: Aventurine is a quartz mineral that is most often used to crave ornate animal or spiritual figures. Aventurescence is a term used to describe the shimmering of this stone that is caused by mica inclusions. The color is almost always green, however sometimes it is blue, or green with hints of blue, or brown. Aventurine is ideal for the carving of figures, but not the best material in the world for (read full)

Rock Crystal (Quartz)

Rock Crystal (Quartz): Rock Crystal is the purest water-clear and colorless from of Quartz. It is known as mountain crystal (Bergkristall). It is the presence of impurities that gives other varieties of quartz their colors. It is found in beautifully formed crystals, often with complex terminations. These are usully bounded by the faces of six-sided prisms, which are almost always striated horizontally. Very often they (read full)

Indicolite

Indicolite: Indicolite is the blue sodium-rich variety of Tourmaline, and may come in all shades of blue, from light-blue, violet-blue to deep red or deep green. It generally appears quite a deep blue, even the color of dark blue ink, perhaps appearing green in one direction because of its strong pleochroism. Sometimes indicolite is an overall greenish blue, which, unlike the color of greenish blue sapphire, (read full)

Celestine

Celestine: Celestine appears as colorless, or pale blue, and is transparent to translucent, and has two directions of cleavage. It is very brittle, and has a vitreous to pearly luster. It occurs in sediments associated with sulfur, with evaporate minerals like gypsum, anhydrite, and halite; in hydrothermal veins with galena and sphalerite; as concretions in clay and marl; in cavities in basic lavas, and i (read full)

Orthoclase

Orthoclase: Orthoclase mineral is a silicate of potassium and aluminum, belonging to the Feldspar group. It has the same composition as microcline, but is stable at slightly higher temperatures.
