A very rare specie from Mina Ojuela ex Charles Noll, Crawford and Seaman Museum. etc. A transparent white crystal spray sits nestled in a mossy green matrix of Mottramite and characteristic Ojuela blocky Wulfenite. Better known from Tsumeb where it is one of the rarities sought much sought after, however the type locale for this mineral is in Alamos, Mexico.
Apatite -CaF (Fluorapatite)
Cerro de Mercado, Victoria de Durango
4.9 x 3.5 x 3.2 CM (miniature)
Pre Holiday 2017
An older Apatite from Cerro de Mercado that presents a fine 3.5 CM gemmy crystal well exposed on matrix. This locale was a prolific source of these Apatites although most were much less clear than this and few on matrix. Rich yellow-green (asparagus) color. A choice piece in good condition that looks better in person. One old rehealed break is seen in the main crystal. A nice example.
An old Italian specimen that is loaded with several well crystallized rarities. Included older labels have misidentified the Metastibnite as Kermesite which it does indeed look like. Aside from that, this hosts well developed crystals of Klebelsbergite in several forms, Peretaite, Sulphur, Stibnite, Valentinite and possibly Ottensite and Minyulite. A real treat under the microscope, but the largest metastibnite crystal is 2.8 CM and needs no magnification.
