BOURNONITE FROM CHINA

Fifteen to twenty years ago bournonite specimens from China were readily available, yet quite expensive. The Yaogangxian Mine was producing fine specimens then, some worth up to $1 million. 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" habit.

Included in this gallery is bournonite for sale from the famous find many years ago at the Yaoganxian Mine in China. Bournonite is a trithioantimoniate of lead and copper and is categorized as a sulfosalt mineral. Bournonite is most famous for cyclic twinning resulting in the cogwheel habit. Below are bournonite specimens acquired last year from Georg Gebhard, the famous mineral collector and authority on Tsumeb. Bournonite from China first appeared on the mineral market in 1989 with erroneous locality information, probably caused by Chinese dealers trying to conceal the true source of the bournonite crystals. After about 4 years it was finally revealed that they originated from the Yaoganxian Mine. Gebhard and other German collectors obtained these in the late 1990s when it was possible for collectors to lease the mine for specimen collecting. Gebhard used these for trading with mineral museums and mineral collectors. The size and quality of these bournonite crystals is exemplary and few are available from other sources these days.
