Azurite from Milpillas Mine, Cuitaca, Sonora, Mexico [db_pics/pics/d111c.jpg]

Large single crystal likely from the Milpillas Mine. This was shipped to me directly from Mexico from a miner who claimed it was from Sierra Rica, however it looks more like a Milpillas Mine crystal. At any rate, it's a big, showy single crystal crystallized on all sides, front and back, with some bits of matrix intergrown in areas.

Mottramite over/after Quartz from Mina Oujela, Mapimi, Durango, Mexico [db_pics/pics/d126d.jpg]

Oujela Mottramite is common enough, but I've never seen a specimen from here of Mottramite over Quartz crystals. There are numerous crystals of Quartz that are either covered by or replaced by Mottramite. There is Quartz at the base of the specimen, but when I look closely at the bottoms of the crystals at the edge, I can see no Quartz in the cores, which leads me to believe the Quartz has been replaced by Mottramite.
