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, gem/gemmy, slightly hydrothermally etched, rich blue color crystal from one of the more obscure localities for the material in the world. Ex. Richard Kosnar Collection.
