Rare Double-Terminated Beryllonite Crystal – Afghanistan

Beryllonite is a rare sodium beryllium phosphate that is seldom found in well-formed crystals. This 216.3ct specimen from Afghanistan is an exceptional outlier, boasting a robust Double-Terminated habit. This means the crystal grew freely in the pegmatite pocket, allowing it to form natural, finished points at both ends.

The crystal displays a beautiful tabular-to-prismatic geometry with the characteristic pearly-to-vitreous luster that defines the species. Its translucent-to-transparent body allows light to play across the complex, etched surface faces, highlighting its natural, untreated state. For the collector who focuses on rare beryllium minerals or high-end Afghan specimens, a double-terminated Beryllonite of this magnitude is a definitive "holy grail" piece.
