Description

This is surely our best specimen when it comes to bright green colored botryoidal kolwezite on dark but translucent to transparent purplish red cobaltoan dolomite crystals. We've only seen a couple of specimens of this kind and this is probably even better than the one we offered before - with only a few minor dings at the sides.
