La Union Mine, Sierra de Cartagena
5.8 x 3.3 x 2.6 CM (cabinet)
Late Summer 2018
Remarkable, perfect and esthetic. Free standing rosettes of Barite crystals on a rough matrix arranged in a line. This locale has produced a lot of nice Barite specimens but very few have anything close to this elegant perfection. Under 40X magnification there are no chips or damage seen, which is incredible with such a delicate mineral in thin bladed crystals. Better in person too.
A very rich specimen of several uncommon Copper species, most importantly Lavendulan. Also containing a sizable zone of Conichalcite, minor Azurite and what appears to be Barahenaite (not analyzed). The Lavendulan is present in thick bands, crusts and small crystals of several habits. The Conichalcite is in translucent green globules covering one entire face. Lavendulan is a Phosphate and also an Arsenate, with the complex formula ofNaCaCu5(AsO4)4Cl·5H2O. Not often seen on the mineral market except in small blebs or micromounts.
