MMX6 Cobaltite 
Hakansboda, Lindesberg, Västmanland, Sweden
4.8x 4.5x 4.3 cm

$300

A large cobaltite crystal, frozen in a chalcopyrite matrix, from a classic locality.  These specimens are very hard to obtain, much more so than the Canadian cobaltites which pop up every now and then.  Plus, this one is priced at about half what you will find anywhere else online.
