Native Copper with Cuprite & Calcite Tsumeb, Namibia 6.34cm x 3.1cm x 2.55cm Ex. Neal Wintringham Collection

Description/Interesting Notes: A terrific example of native copper with cuprite and calcite from Tsumeb!!! This specimen hosts a showy network of sharply formed native copper crystals paired with ruby red crystals of cuprite and complex, lustrous calcite crystals!!! The native copper crystals exhibit highly complex forms with razor-sharp faces and an almost golden, slightly iridescent patina!!! The cuprite crystals are present as complex groups of modified cubo-octahedral crystals with rich red color!!! The calcite crystals are present in two generations with a layer of tiny crystals underneath a network of blocky, complex, highly lustrous calcite crystals!!! The larger calcite crystals fluoresce a lively orange-red under SW UV, whereas the tiny crystals do not!!! There is also a small amount of tan colored mimetite in minor association as well!!! This specimen is in magnificent condition and displays fantastically all around!!! The pics hardly do it justice!!! Must be seen in person to be fully appreciated!!!
