A species of Minerals, Also known as Operment, Arrhenicum
Orpiment is a fairly rare mineral that usually bears a striking golden or yellow-orange hue. Historically, this arsenic-containing mineral was used until the 19th century when it was replaced by less-toxic options. Specimens of orpiment with large, striking crystals may be sought out by collectors. The mineral is also used today in the production of semiconductors and photoconductors.
