Rosasite pseudomorph after Malachite after Azurite (very rare locality)

Item Description

An incredibly hard to find specimen from the Uncle Sam Mine, which lies a little over a half mile southwest of Bisbee. Specimens from this locality are virtually unseen on the market, and this piece is a really cool multi-generational pseudomorph, reminiscent of the classic material from Tsumeb featuring rich blue colored Rosasite which is replacing Malachite that has already replaced Azurite. The largest crystal measures about 7 mm, and it's truly the ONLY specimen we've ever had to offer from this locality. There is a label from an unknown collection that states the piece was collected in December of 1986, presumably off the dumps of the mine.

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).
