Brochantite

Locality: Shattuck Mine (Shattuck-Denn Mine; Shattuck-Arizona Mine; Denn Mine), Bisbee, Warren District, Mule Mts, Cochise Co., Arizona, USA

This is a huge mass of intergrown lathe-like, lustrous, deep, emerald green, brochantite crystals, to 2.75 cm in length. Over an inch crystals! This is incredible size and richness for Bisbee! Brochantite, a hydrous copper sulfate, is usually found in tiny crystals as a rare secondary mineral. But this specimen is mind boggling for its size and quality. It is made more precious in that it originates from Bisbee. Formerly in the collection of Ken Hollman, until his untimely passign 2 years ago. 8.7 x 7.8 x 6.3 cm
