This small thumbnail specimen consists of a quartz-and-pyrite base on which rests a thin crust of Native Selenium. This crust shows no visible crystal form and is only discernable by its dark, violet-gray coloration. It is dull in luster and likely opaque. It coats a few botryoidal quartz formations that are on the piece and is accompanied by a few broken chalcopyrite crystals, along with the pyrites that are embedded in the quartz.
