Dolomite after Tarnowitzite with Copper on Dolomite cast (Ref: P272)

Tsumeb, Namibia
45mm x 45mm x 35mm
$500
A really interesting and classic Tsumbe combo specimen of multiple species. At first glance this appears to be 'just' a Dolomite cast, however upon examination you see a number of attached white pseudomorphs of zincian Dolomite after Tarnowitzite. There are two such pseudomorphs on the top surface and another two on the bottom surface. Also present are small green altered Copper crystals (the red metallic Copper color showing through on some crystals). On the bottom surfaces are areas of light green crystals, possibly Smithsonite. Ex. Carl Acosta collection and comes with a few old labels.
