This more than likely the finest color Aquamarine from North America. Some of this material was mined by Richard Kosnar in the late 1970's and produced some of the finest color Aquamarine in the world. Most of these crystals are not gem quality, but this crystal is approximately 85% gem clarity. This crystal is a fine, sharp, very gemmy, lustrous, hydrothermally etched, rich blue color crystal of Aquamarine from one of the more obscure localities for the material. Ex. Kosnar Collection.
