- Paprok Mine, Kunar Province, Nuristan, Afghanistan
- Toenail, 3.0 x 0.8 x 0.2 cm
A truly exceptional, totally transparent gem crystal of this incredibly rare species. Crystals of this size are probably limited to sevral dozens at a guess, and few are of such quality and sharpness (most being rather opaque). This is a stunning, rare treasure from the pegmatites of Afghanistan. Joe Budd Photos.
