Talk about a rare sulphide! Ferrokësterite is found in only a handful of localities worldwide, but the ones from San José mine in Bolivia are among the best for the species, although they are usually rounded off like this one. This excellent group of white-metallic tetragonal crystals make for a superb miniature.
