Linarite (ex Kay Robertson Collection)

Item Description

A really cool old time specimen from the lesser known Cerro Gordo (Fat Mountain) Mine in California featuring lustrous, somewhat chatoyant, deep midnight blue color, shimmering, semi-prismatic, crystalline groups of Linarite associated with what I believe is green Brochantite on matrix. It's not common to find crystals on matrix from this locality, so this is a good representative specimen of this beloved lead copper sulfate from this now ghost town locality near Keller. A very attractive piece for what it is, and a worthwhile pickup for anybody who likes secondary ore minerals, or California minerals. Ex Kay Robertson Collection (#4243). Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record). A beautiful and attractive old-timer from this lesser known locale.
