Description

This awesome little cluster of tetrahedrite var. tennantite looks straigt like from outter space. The highly metallically lustrous crystals are arranged in a super cool way, reminding a bit of the golden robot C-3PO from Star Wars. This golden effect is due to a partial layer of extremely lustrous chalcopyrite that is covering the specimen. Definitely an eye-catching specimen in fantastic condition.
