Chemistry : Cu₉Si₁₀O₂₉ 11H₂O
Rarity : Very rare

Apachite is an extremely rare hydrated copper silicate which forms small fibroradiated spherolites composed of tiny crystals of a magnificent sky blue. It owes its name to the Apache Indians, inhabitants of the discovery region : the Christmas Mine (Arizona). It is a metamorphic mineral found in tactites (calcium hornfels) replacing an assembly of garnet, diopside, calcite and sulphides.

Apachite in the World

Apachite is found in small spherolites at the Christmas Mine (Arizona) its type locality, and in crusts and encrustations at Alforja Mine (Spain), Kandesei (Namibia) and in the Agardag Massif (Russia).
