Not from the Bruckner Collection, but something I had to get posted soon anyhow...this is a fantastic cerussite crystal from Tsumeb, of a very rare style. The color , blood red, is due to minute iinclusions of cuprite inside. Such cerussite came from only a few pockets, and this is the rarest of styles for the color - a "normal" cerussite twin as opposed to the usual etched, elongated, or melted-type appearance this material usually takes. Complete on both sides, translucent, and just breathtaking for color, this is one of the finest Tsumeb thumbnails I have had the pleasure of handling, for my tastes. It is indeed expensive, no question, but its unique. I had this first perhaps 3 years ago, and was recently able to trade it back from the owner.
