Ken had this marked as Ajo Mine but I must assume it is the Ajo Mining District and likely the New Cornelia Mine. This miniature shows two distinct sharp crystals to 2.5cm with excellent color. The contact on the right hand crystal must have been in situ as the conchoidal area is pseudomorphed to malachite. Ex Ken Roberts collection.
Locality: Ajo Mining District, Pima County Arizona
Composition: Copper Carbonate
