(about 15 inches tall and 9.7 pounds weight) This fanspray of finely-crystallized copper weighs in at just about 10 pounds and is impressive as hell. It is COMPLETE all around, fully crystallized front,sides, and back. It has Carnegie's collection number as well as several yet older collection numbers attached to the backside. Look at the pics, than lift a bowling ball to try to get a feel for the size and weight of the specimen, and thus by inference its visual impact! You can clearly see this specimen laying in the middle of the very bottom shelf of the leftmost of the two cabinets flanking the fireplace in the top photo of the mansion's dining room.

ONLY FROM TSUMEB! This is a very unusual combination of mineral species, at Tsumeb or anywhere to my knowledge. Crudely formed copper crystals with a fine patina frame many intergrown crystals of lustrous and translucent, gemmy smithsonite, to 1 cm across. Several of the sharp smithsonite rhombohedra are included by copper, something I have not seen before in this habit. Copper is actually quite rare at Tsumeb, in native form.
