Some information about bismuthinite:

Bismuthinite is a mineral consisting of bismuth sulfide (Bi2S3). It is an important ore for bismuth. The crystals are steel-grey to off-white with a metallic luster. It is soft enough to scratched with a fingernail and rather dense.

Bismuthinite occurs in hydrothermal veins with tourmaline-bearing copper veins associated with granite, in some high temperature gold veins, and in recent volcanic exhalation deposits.

It was first reported in 1832 from the mines of PotosĂ­, Bolivia (More information about bismuthinite).
