Description: Aggregates of calcite with quartz crystals and chalcedony on a basalt matrix. When looking closely through good magnification, one can see a tinge of blue-green colouring in the chalcedony. Strong magnification also reveals minute hematite specks (some red) in most of the quartz crystals.
This is one of only two specimens we have from a rare find, and we (and some of the Brandberg experts) haven't seen any other either.
The specimens has very little damage - only a few small nicks.
