The Deal with Diaspore

This rare 26.04-ct. color-change diaspore from Anatolia, Turkey, has found a new home at the Gemological Institute of America. Guven Cankur of Color Change Empire, owner of the mine where the diaspore was found, donated the gem under GIA's Treasured Gifts program. Turkish diaspore exhibits dramatic color changes, from brownish green to green in daylight to rich champagne (shown here). Other diaspores can change to more reddish tones. Diaspore registers 6.5-7 on the Mohs hardness scale and has a refractive index of 1.702-1.750 and specific gravity of 3.39. These characteristics make it an excellent candidate for mounting in jewelry. But its greatest selling features are the color change, durability, scintillation and color saturation. Color Change Empire Inc., New York City; (212) 533-5676.
