Achroite Tourmaline
Gems and Jewelry, 10.6 x 8.8 mm; 4.86 cts

Achroite is the colorless variety of Tourmaline, and is not found is great quantity from any locality in the world. Colorless Tourmaline is an indication of the purity of the material as there are little no to imperfections in the chemical formula to create color. This is often the case with many gems as impurities (chromophores) actually allow the stones to have their vibrant hues. This stone is an attractive little Achroite gem that is virtually eye clean with an "Emerald" cut. You don't see many of these stones on the market these days, and it would make a great addition to any Tourmaline suite to show the diversity of colors (or lack thereof) for this highly popular gemstone.
