Mineral Type - Garnet - Andradite / Demantoid

Andradite is named after the Brazilian mineralogist J. B. de Andrada e Silva (1763-1838). Demantoid is named after its adamantine luster. This garnet is commonly called Demantoid Garnet. Rich green colour which ranges in intensity. Toprock gets fairly regular batches from Namibia with only a handful ever coming out of Madagascar. Namibian specimens tend to be plate like specimens having drusy small crystals on exposed surfaces. Only a small % of specimens have larger more distinctive crystals. A very rare species for the collectors.
