Bismuthinite, Ferberite, Stannite, and Quartz
Very rarely seen together, this magnificent combination specimen features several large, superb crystals of Bismuthinite with associations of Ferberite, Stannite, and needle-like Quartz points, all atop a thin and robust matrix. The Bismuthinite is mainly presented at the center and top of the specimen, reaching 6.4 centimeters in length. Each crystal is sharply-formed and heavily caked with microcrystals, giving the Bismuthinite a uniquely lustrous visual. A small handful of large, lustrous, striated Ferberite crystals (up to 4.8 centimeters) are grouped together on the right edge of the specimen's front. One of the more impressive features is the Stannite, which is strewn across the specimen as dark, brassy botryoidal clusters and (hardly ever seen) crystals. There are a few potential associations of Chalcopyrite. This piece comes with a custom acrylic base.
