Cuprite (Var: Chalcotrichite) on Chrysocolla, Bisbee, Arizona, USA
Chalcotrichite (from the Greek, “copper hair”, in old-timer days known as “wire copper”) is an uncommon, highly coveted variety of the copper oxide cuprite. This eye-catching specimen from the world-class Bisbee mining district pairs sparkly, crimson chalcotrichite crystals on a bed of nicely contrasting, baby-blue Chrysocolla. The public archives of Mindat contain only one other instance of this occurrence. Sourced from a 40+ year-old collection.
