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 50% gem clarity. This crystal is an attractive gemmy, lustrous, hydrothermally etched, rich blue color crystal of Aquamarine from one of the more obscure localities for the material. One simply does not see these specimens offered very often. This specimen was collected in the 1970's by Richard A. Kosnar.
