Conichalcite (barthite - 1975 find)

Item Description

Scintillating, gemmy, luscious forest-green conichalcite crystals are festooned in the sculptural vug in sturdy gossan matrix on this extra fine specimen from the well-known around 1975 find at Mina Ojuela. The older label lists this as cuprian austinite (barthite), but research has shown this to be primarily conichalcite. See the Ojuela Mine Mineralogical Record Special Issue, Vol. 34, # 5, Sept-Oct., 2003. Rare in this fine quality, this is a highly unusual specimen!
