Pyrite ps. after Pyrrhotite

Item Description

A hard to find specimen from the Rosebud Mine (Hecla Rosebud Mine) in Nevada featuring beautiful "rosettes" of what were once Pyrrhotite, but have been pseudomorphed by metallic golden Pyrite. The largest individual crystal on the specimen measures 1.5 cm across. If you look closely, you can see that several of the pseudomorphs are actually hollow "casts", where the Pyrrhotite has completely been dissolved away, leaving only the Pyrite "shell" on the exterior. Small off-white colored spheres of what looks like Dolomite(?) are present on the piece as well. This is quite possibly the first specimen we've had of this material to offer in the auctions, and if you collect pseudomorphs of minerals from the Western United States, don't miss out on this beauty. From the collection of Gary Weaver of Prescott, Arizona (1944-2019). Gary was an electrical engineer who worked for many years for Hughes Aircraft in California. After retiring to Prescott, Arizona in the early 2000s, Gary rekindled his childhood love of minerals, amassing a collection of roughly 2000 specimens focusing on localities in which he and his wife had lived or visited (Mexico, Peru and the western / southwestern United States).
