Andorite on Stannite
San Jose Mine, Oruro City, Oruro Department, Bolivia
Cabinet, 11.8 x 7.2 x 3.7 cm
Ex. Philadelphia Academy of Natural Sciences
SUPER-bright crystals to 7 mm of razor-sharp andorite, rare in such quality and with such luster to them. This would be from early finds, perhaps even from the Vaux expeditions judging by the Academy accession number. There are bigger andorites, to be sure, then and now. However, as a whole, this is a really beautiful display specimen with iridescent matrix under the andorites. The matrix is stannite in tiny sharp, wildly iridescent crystals atop massive ore. I have not seen another like this!
