Bournonite is a sulfosalt mineral species, trithioantimoniate of lead and copper with the formula PbCuSbS 3. It was first mentioned by Philip Rashleigh in 1797 as an ore of antimony and was more completely described in 1804 by French crystallographer and mineralogist Jacques Louis, Comte de Bournon (1751–1825), after whom it was named.
Bournonite, sulfosalt mineral, a lead, copper, and antimony sulfide (PbCuSbS3), that occurs as heavy, dark crystal aggregates and masses with a metallic lustre in association with other sulfur-containing minerals in many locations, including the Harz Mountains of Germany; a number of localities in
Bournonite was positively identified in 1804 by French mineralogist and crystallographer Count Jacques Louis de Bournon (1751–1825), founder of the Geological Society of London. The name given by Bournon for this mineral was Endellione (later Endellionite), after the Cornish locality where it was first described, but subsequently the name was changed to Bournonite in Bournon's honor.

Bournonite is an uncommon (there are only 138 photos of bournonite from China listed on Mindat.org) sulfosalt mineral, with the formula: PbCuSbS3. Bournonite crystals are commonly complexly twinned, resulting in complex clusters of parallel twinned crystals, with parallel crystal faces, and if cyclic-twinned will exhibit the classic "cog wheel ...
