A very 3-diemnsional specimen, MUCH BETTER In PERSON, with sharp sprays of the rare sulfide semseyite perched off of glistening black sphalerites. The semseyite reaches 1 cm in size individually, though the sprays are larger overall of course. You can see two major sprays of the mineral in the protected crevasse at the center of the specimen between the stalactitic growths of sphalerite, and one is shown in closeup. Superb, especially for the relatively bargain price for this rarity
