From Shigar Valley, Gilgit-Baltistan, Pakistan
The Shigar Valley, located in Pakistan, is renowned for its deposits of alkali-rich beryl, a mineral of significant interest to both mineralogists and gem collectors. The unique geochemical conditions of the region contribute to the formation of this variant of beryl, which is distinguished by its high alkali content. The presence of alkali elements such as lithium, cesium, and rubidium can impart distinctive colors and properties to the crystals, making them highly sought after for both scientific study and their aesthetic value.
