It was down to Carsten to wrap up August 2015, and boy did he find something a bit unusual!
Brunogeierite is an insanely rare iron germanate found only (so far) in a few places, plus Tsumeb. The crystal habit is black octahedral crystals.
For a Tsumeb collector this is one of most sought after species there is.
Associated with this specimen are hair like crystals of carrot orange ludlockite.
We are looking at some strong bidding competition for this one!
