This specimen showcases striking and unusually robust etched alkali-rich blue beryl crystals in association with quartz on the matrix. The beryl crystals are exceptionally well-formed, exhibiting remarkable color, and perfection. The crystals are fine all around with nice etched formations, and display a stunning and unique color contrast, making it one of the finest examples of its kind.

Alkali-rich blue beryl, sometimes called Rosterite or Vorobyevite, is a cesium-bearing variety of beryl that typically forms in granitic pegmatites. Its distinctive blue coloration and tabular crystal habit are attributed to its unique chemical composition, including higher alkali elements such as cesium. These characteristics make it a rare and sought-after mineral among collectors.

The Deo Darrah area, located in the Khash and Kuran Wa Munjan Districts of Badakhshan Province, Afghanistan, is renowned for producing high-quality mineral specimens, including tourmaline and beryl. The region’s complex geological history has resulted in the formation of unique mineral assemblages, making it a significant locality for rare minerals like alkali-rich beryl.

Weighing 160 grams and measuring 8 x 5.5 x 2.5 cm, this cabinet-sized specimen exemplifies the exceptional mineralogical treasures found in the Deo Darrah area. Its size, color, and crystal perfection make it a valuable addition to any discerning collector’s assemblage.
