- Talnakh Cu-Ni Deposit, Norilsk, Eastern-Siberian Region, Russia
- Miniature, 4.0 x 3.2 x 2.1 cm
An important specimen for this rare platinum species, with a crystal of significant size overall for the species from any locality. The cluster is 2.7 cm across and the main crystal on the left is 2 cm across! As with all such larger sperrylite crystals, the surfaces show stress fractures from the crystal growing into surrounding matrix of chalcopyrite and sulfides that is now laboriously excavated away. It is a full-sized, competitive-level miniature. Specimens such as this are simply so far above the mean in importance, that I cannot recall seeing such a significant specimen in recent years. Comes with a custom lucite base. Joe Budd photos.
