A triangular hunk of red-brown mineral with small black and iridescent botryoidal masses on the top. The parts that are metallic are mostly iridescent (ranging the whole color spectrum) but some parts along the left side are black as well. Additional botryoidal masses are black and earthy. If examined closely the dull parts are a layer (similar to a skin) on top of more metallic bits and can be easily peeled off to reveal a colorful underside.
