Description

This is a great rarity from Tsumeb. In the past I had only 3 specimens hosting bartelkeite. The last find of bartelkeite is years ago. Now I was able to obtain one again!

In the picture above you will find bartelkeite forming olive green crystal aggregates among colourless frosted galloplumbogummite "spheres" and another yet unidentified yellow to green mineral.
