- Blue Alkali Beryl
- Miniature, 3.7 x 2.6 x 2.2 cm
- Deo Darrah, Khash & Kuran Wa Munjan Districts, Badakhshan Province, Afghanistan
Aesthetically perched on matrix is a rounded cluster of tabular, lustrous and translucent, aquamarine blue alkali-rich beryl crystals to 2.5 cm across. The largest crystal is also doubly terminated. The specimen is very dramatic, and looks good from two angles although it is contacted on the right side. If it were complete all around, it would easily be worth three times as much. These were originally thought to be Rosterite or Vorobyevite, but further analysis by Dr. Federico Pezzotta confirmed they are alkali-rich beryls.
