This Aquamarine specimen was mined by Richard Kosnar in the late 1970's and his diggings produced some of the finest color, unheated Aquamarine in the world. Most of these crystals are not gem quality, but this crystal is approximately 90% gem clarity, which is very good for the material. This crystal is a fine, sharp, very gemmy, lustrous, rich blue color, slightly etched crystal of Aquamarine from one of the more obscure localities for the material. It actually has very well defined, sharp crystal faces. Ex. Richard Kosnar Collection.
