The specimen shows a well-formed dark sphalerite crystal on a mixed sulfide–silicate matrix. Pyrite is present as small cubic and irregular metallic crystals surrounding the sphalerite. Transparent quartz crystals occur across the matrix as prismatic and blocky forms. Light brown surface coatings are visible on parts of the quartz and matrix.
The main sphalerite crystal is intact, with minor natural contacts typical for the locality.
