Duftite and Calcite

Colorless Calcite rhombs on a matrix covered by green Duftite. I was able to spot a couple tiny Dioptase crystals too. From Tsumeb Mine, a defunct locality in Namibia, that is also the type locality for Duftite.  With a loupe, you can see little Duftite clusters inside some of the Calcite crystals. Really interesting.
