This is a lovely, rich pink, translucent to transparent, well formed, lustrous, tabular, crystal of beryl. This is the newly discovered and named Pezzottaite, or cesium-rich beryl species. I bought this from the very first finds, before they were even identified as a new species in 2002, and sold it to Irv at that time. Today, they are obviously much more expensive but beyond that, good symmetric crystals are hard to find.
