1.35" Gemmy Andradite Garnets with Diopside - Afghanistan

Gemmy Andradite Garnets with Diopside - Afghanistan #290361

This is a gorgeous, 1.35" wide association of several large, deep brown andradite garnet crystals with deep green diopside crystals in a soft matrix. The garnets are partially coated by an unidentified beige mineral. This specimen has been mounted with mineral tack for museum-quality display.

This specimen comes from the Ghunday talc deposit in the Nangarhar province of eastern Afghanistan. It is 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. This deposit produces the highest quality talc (99% purity) in the Spin Ghar mountain range, as well as a variety of minerals that include andradite garnet, clinochlore, diopside, epidote, magnetite, and vesuvianite.
