This is a tower of 3-dimensional, jet-black crystals to 4.5 cm. The piece is complete all around, 360 degrees, like a pyramid! The wet-looking patina, in contrast to the usual dull gray we see on Tsumeb tennantites, is striking and different and really makes the piece leap out as a cut above other Tsumeb examples of this species. Its a world class example of the mineral, from one of the premier localities. This collection was always known for its breadth of specimens but also noted within the community for two very fine pieces of extremely high display quality that were sold to Ed out of the personal collection of Miriam and Julius Zweibel: a smashing wulfenite specimen with metallic orange luster (now in the Marshall and Charlotte Sussman collection); and this fantastic tower of stereotypically sharp crystals. Ed retired and moved away from Dallas in 1984 or so, taking these with him. The piece hasn't been seen outside of his homne since then, and it shocked me when I first saw it.
