D126 - Mottramite over/after Quartz $ 180 Mina Oujela, Mapimi, Durango, Mexico small cabinet - 5.5 x 3.5 x 3.5 cm ![]() ![]() ![]() ![]() 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at the bottoms of the crystals at the edge, I can see no Quartz in the cores, which leads me to believe the Quartz has been replaced by Mottramite.
