Description/Interesting Notes: A LARGE and EXTRAORDINARY example of native copper with molybdenite and quartz from Namibia!!! Please note - this is a BIG specimen and WAAAAYYY better than the pics show!!! This specimen hosts large, highly complex cryst...als throughout and is very impressive in person (please be aware that these pics are of a large specimen with robust crystallization!)!!! This is one of the most significant examples of native copper I have seen from Namibia - and it is made even more impressive, significant, and unusual with the association of molybdenite (YES, molybdenite!)!!! This specimen is loaded with complexly intergrown, modified cubic forms (the cubic forms are much more evident in person, and characteristic of the locale) that exhibit complex surface detail with marked luster and a handsome patina!!! The underside/reverse of the specimen shows numerous intergrown quartz points and masses of silvery metallic molybdenite (confirmed material) crystals with quartz!!! Upon close inspection with a loupe or scope one can see all the characteristic features of the molybdenite crystals as well!!! There is a small amount of an unidentified green mineral present as well!!! All of the copper is well crystallized and this large and impressive specimen (weights a hefty 2.36Kg!) displays magnificently in person!!! The Onganja Mine is a copper-molybdenum porphyry mine - I have never seen this assemblage before and this is the only locality to my knowledge where it occurs (although it is still quite rare to find them intergrown like this)!!! This is a museum worthy specimen to be certain - do not miss out on this incredible opportunity!!! The pics hardly do it justice!!! Must be seen in person to be fully appreciated!!!Good luck and be sure to check out my other exciting mineral auctions on ebay!!!
