This rare sodium beryllium phosphate is often found in smaller, nondescript specimens from various other pegmatite localities around the world, but the specimens from Afghanistan are incredibly well formed, large and beautiful. This piece is a good sized, sharp, well formed, euhedral, pseudo hexagonal (monoclinic) crystal group of Beryllonite showing the typical
