Here is a first-class specimen of a perfectly formed black brunogeierite specimen. Brunogeierite is one of the largest rarities in the Tsumeb mine. Only extremely few pieces are known in this perfection. The crystal shows an ideal all-round formation with a beautiful shine. A smaller crystal is attached to the main crystal, which gives the whole thing a special character.

It should be emphasized that this crystal is not microscopically small, but with its edge length is a giant for its kind!

Brunogeierite is a type locality mineral in Tsumeb Mine and is only known from a few localities worldwide.

Ex. Adolf Popp specimen. 

Important note: The specimens are from the renowned collection of Dr. Gerhard JUNG (Hagendorf specialist, after whom the mineral Jungite was named). Dr. Jung was very meticulous regarding the provenance of his pieces. The previous owner is often noted - it is noticeable that Dr. Jung apparently had good contacts with the famous Tsumeb collectors Walter Richard KAHN (Warikahnite) and Wolfgang BARTELKE (Bartelkeite) from the early 1970s to the late 1980s. Many of the pieces originally came from the hands of the aforementioned pioneers. The specimens of the JUNG collection with first-class and documented provenience are presented here.
