Roquesite with Stannoidite Pravourmiyskoe, Boureinsky Massif, Khingan-Okhotsky region, Russia 2.5cm mount(specimen measures 1.35cm)

Description/Interesting Notes: A fantastic, meticulously prepared example of this very rare copper indium sulphide from Russia!!! This specimen consists of a carefully prepared 2.5cm probe mount that contains a brilliantly metallic example of rare roquesite with stannoidite in association with chalcopyrite, arsenopyrite, native bismuth, cassiterite, and quartz!!! Roquesite is an extremely rare copper indium sulphide - there are only a very small number of indium bearing mineral species!!! Specimens of roquesite are quite difficult to obtain, let alone well-confirmed and prepared examples such as this!!! This specimen is accompanied by two SEM backscatter images as well as X-ray spectra and additional info!!! Rare material from a rare Russian locality as well!!! RARE!!! The pics hardly do it justice!!! Must be seen in person to be fully appreciated!!! Good luck and be sure to check out my other exciting mineral auctions on ebay!!! STAY TUNED!!!
