An absolutely ugly fluorite cluster serves host to some absolutely fantastic locality ferberite crystals, that are sharp and well formed from any place but particularly rare in the suite of minerals found in the Erongos. Charlie valued this highly and took care to point it out to us in the collection. These ferberites, he said, were the best he was ever able to obtain and frankly I had NEVER even heard of such crystals being reported from the region so I was shocked.
