While small, this is a beautiful specimen of goshenite, the colorless crystalline variety of beryl. It consists of multiple distorted hexagonal flat crystals stacked into a book. I can discern at least 8 distinct crystals, although two of them dominate. The goshenite crystals are very transparent, and completely colorless, and have a vitreous luster. There are also at least three long thin crystals of dark green elbaite tourmaline, the largest of which extends 1cm beyond the host goshenite.
