This specimen consists of a small spray of thin, radiating Kermesite needles that rest on a dense, gray, metallic host rock. These needles do not exceed 0.4" (1.0 cm) and appear to be in moderately good condition, though there seems to be a patch of broken crystals that may have made up another spray when they were intact. These needles have a dull, violet-red coloration and show a rather dim adamantine luster due to their compactness, and may be dimly translucent, though that is difficult to determine. Oddly enough, their point of convergence is about 3 mm above the host rock's surface. They rest in a shallow depression in the host rock that is lined with a dull, bright-yellow crust that is very thin. The host rock itself is massive and gray, and shows scores of tiny hollows in which extremely small gray, metallic needles rest. I really don't know what these could be made of, either. Given the sulfur content of the Kermesite, I would be inclined to think that the crust was made of sulfur, and that the tiny needles were made of some sort of antimony sulfide mineral such as stibnite.
