Anunusually elongated, very large, dark purple crystal from the Gobobos. If this crystal was gemmier, it would be a $10,000 specimen. It is still a wonderful example, quite translucent and colorful when backlit, if not transparent. The size is remarkable, for the condition (pristine, save for some ingrown matrix attachments on the backside). Major amethyst from here, without breaking the bank.
