This Aquamarine specimen was mined by Richard Kosnar in the late 1970's. 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 certainly gemmy when backlit, which is very good for the material. This crystal is a fine, sharp, somewhat lustrous, slightly hydrothermally etched, rich blue color crystal of Aquamarine from one of the more obscure localities for the material. Ex.
