Bismuthinite

Bismuthinite is a mineral consisting of bismuth sulfide (Bi2S3).

The crystals are steel-grey to off-white with a metallic luster.

Bismuthinite forms a series with the lead, copper, bismuth mineral aikinite (PbCuBiS3).

Associated minerals include native bismuth, aikinite, arsenopyrite, stannite, galena, pyrite, chalcopyrite, tourmaline, wolframite, cassiterite and quartz.
