Chalcoalumite, Azurite
Cabinet, 11.1 x 8.5 x 4.8 cm
Copper Queen Mine (Halero Mine), Queen Hill, Bisbee, Warren District, Mule Mts, Cochise Co., Arizona, USA
SOLD
A fine, old-time, cabinet specimen from the Copper Queen Mine at Bisbee. Two grottos or caves and a nearby wall on the sturdy gossan matrix are lined with sparkly, tiny, electric-blue to royal-blue azurite crystals. The starkly contrasting "grass" in the "front yard" is botryoidal, pastel-green chalcoalumite. Chalcoalumite is a rare copper, aluminum sulfate and the Copper Queen Mine is the Type Locality. This is undoubtedly old material, dating from the late 1800s-early 1900s, but no proof. Ex. Dennis Mullane Collection.
