Quartz crystals (smokey and Amethyst) replacing a long Anhydrite crystal from Brazil. This rare pseudomorph has alot of character. The shape of the former Anhydrite with Quartz crystals along the edges reminds me of a chain saw blade. Translucent to transparent, pristine with an abundance of life, a truely unique specimen. Comes with an old Ken Roberts label.  Ken is a mineral dealer noted for his high level of taste and aesthetics.
