Acanthite crystal growths (selenium-rich) with the dominant faces being the rhombododecahedron, an unusual form for the species, some of them with hoppered growths, associated with Polybasite crystals, likewise rich in selenium, Calcite, and coatings of small Pyrite crystals. Analyses of the specimen, of which we will send a copy to the buyer, indicate a high content of selenium in both the Acanthite and the Polybasite.
