Alkali-rich blue beryl, sometimes called 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 26 grams and measuring 4 x 3 x 2.5 cm, this miniature-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.
