- Blue Alkali Beryl
- Miniature, 3.2 x 2.0 x 1.5 cm
- Deo Darrah, Khash & Kuran Wa Munjan Districts, Badakhshan Province, Afghanistan
Two, tabular, lustrous and translucent, sky blue alkali-rich beryl crystals, to 2 cm across, are nicely perched on smaller opaque crystals. The largest crystal is also doubly terminated. This is a toenail/miniature with more volume than most, and displays dramatically all around 360 degrees. These were originally thought to be Rosterite or Vorobyevite, but further analysis by Dr. Federico Pezzotta confirmed they are alkali-rich beryls.
