A non-Kalahari Key piece that got into this update by mistake, but I'm going to leave it in...this is a super quality, bluecapped tourmaline crystal from small old finds at the Otjua Mine. This crystal is a floater, complete all around and even terminated on the bottom in a series of unusual crosshatched crystal growth patterns. It is gemmy throughout, with very complex color changes. I have never seen one as good, and Charlie says they are quite rare. This is the best one he had obtained and kept.
