Marrite (unique to Type Locality) ex Feinglos Coll.

Item Description

A validated specimen of this ultra rare silver-lead-arsenic sulfosalt species UNIQUE to the famed Lengenbach Quarry. Mark Feinglos exchanged it from Dr. Jaroslav Hyrsl, who in turn obtained it in trade from the Natural History Museum in Bern, Switzerland, in about 1995. Although microcrystalline, the specimen has some display value - more than most such. The two arrows point to the marrite microcrystals (one or two at each arrow). The rest is galena. The marrite is dull on the surface, as opposed to the galena, which is bright. There are also pyrite crystals on one end of the marble. Ex Dr. Mark Feinglos Collection, a well known rare species collector. Valued at $400. Really microscope stuff, but very rare, and a silver mineral, so likely of interest to some folks. (TYPE LOCALITY)
