1.9" Diopside and Epidote Crystals on Calcite - Afghanistan
This is a beautiful, 1.9" wide association of yellow-green diopside crystals and translucent green epidote on calcite.
This specimen comes from the Ghunday talc deposit in the Nangarhar province of Afghanistan. It's located on the north slopes of the Spin (Speen) Ghar mountain range where metamorphic rocks including amphibole, gneiss, marble, quartzite, and marble are intruded by Cretaceous plutonic rocks.
