Ustarasite
Ustarasite is a rare sulfosalt mineral with the chemical formula Pb(Bi,Sb)6S10. It is composed primarily of lead, bismuth, antimony, and sulfur, and belongs to the sulfosalt mineral class. Structurally, it is classified under the Strunz system as 2.JB.40e and under the Dana system as 3.8.11.1. Ustarasite typically exhibits a metallic luster and is known for its dark gray to black coloration. It has a relatively low hardness on the Mohs scale and a moderate to high density. The mineral is part of a broader group of complex sulfosalts that often form in hydrothermal environments.
Overview
Ustarasite is a rare sulfosalt mineral with the chemical formula Pb(Bi,Sb)6S10. It is composed primarily of lead, bismuth, antimony, and sulfur, and belongs to the sulfosalt mineral class.

The mineral is part of a broader group of complex sulfosalts that often form in hydrothermal environments.
Etymology
Ustarasite is named after the Ustarasai bismuth deposit, the location of its discovery. The name reflects the mineral's origin and is tied to the specific locality where it was first identified.
How to recognize it
Ustarasite can be identified by its metallic luster and dark gray to black color. It has a relatively low hardness on the Mohs scale, which can be tested with a standard hardness kit. The streak of the mineral is typically dark, and its density is moderate to high. Due to its rarity and similar appearance to other sulfosalts, it can be confused with minerals such as bismuthinite or other lead-antimony sulfides. Careful chemical analysis is often necessary for accurate identification.
Trivia
Ustarasite is notable for its complex chemical composition, which includes lead, bismuth, antimony, and sulfur in a specific stoichiometric ratio. The mineral's name is directly linked to its type locality, the Ustarasai bismuth deposit, which is a rare and specific reference. Additionally, the mineral's IMA status is questionable, indicating that its recognition within the mineralogical community is not fully established.
