1.8" Demantoid Garnet Cluster - Tubussis Farm 22, Namibia

This is a beautiful aggregation of andradite var. demantoid garnets that were collected from Tubussis Farm 1.82 within the Erongo Region of Namibia.

Demantoid is a variety of andradite, which in itself is a variety of garnet. The chemical composition of demantoid is Ca3Fe2(SiO4)3, with the natural substitution of chromium attributing to the green color of this garnet. Ferric iron is the cause of the yellow in the stone.
