Bournonite (rare locality piece) (ex Francesco Bedogne Collection)

Item Description

This is rarity based on the locality if nothing else. I've never seen a specimen of Bournonite from the Bonanza Mine at Concepciun del Oro, and for what it is, I have to say it's an impressive specimen. A sharp, lustrous, striated, prismatic, silvery colored crystal of Bournonite measuring 9 mm along with a few accessory Bournonites is nestled among Quartz and Calcite on Sphalerite matrix with Golden pyriothedral Pyrite. If you collect sulfides / sulfosalts or Mexican minerals in general, these are incredibly difficult to find on the market, and certainly worth picking up. From the worldwide collection of famed Italian mineral collector, field collector and author, Francesco Bedogne of Sondrio, Italy (Collection #58). Bedogne wrote dozens of articles and several books about the mineralogy of Italian Alpine localities such as Val Bregaglia, Val Masino, Val Codera, Val Spluga, Valtellina and the famous Val Malenco. He was also the founder of the Valtellinese Mineralogical Institute.
