This is an excellent thumbnail specimen of rammelsbergite, considering that there are no distinct crystals. The form is massive, and the color is an excellent silvery-white. One face of the specimen has a very unusual radial pattern of narrow columns with basal striations. My first impression was that it looked like a fossil shell, however the pattern extends into the specimen so it must result from mineral growth. There are other minerals present, red and transparent on one side, black, sparkly and transparent on the other, and some colorless mineral. All of these might be variously colored calcite, or something else entirely. I could not find good crystals to examine.
