A druse of transparent badalovite crystals of beige caramel color with small shiny black crystals of hematite accruing on badalovite. On some vertices of the badelovite crystals, white crystals of aphthitalite are epitaxially grown. On badalovite sometimes grow red-brownish small crystals of cassiterite. FOV in height 6 mm.
