This matrix specimen is mostly comprised of classic, cogwheel twinned Bournonite crystals to 2.0 cm across. The crystals have a matte battleship-metal hue and luster to them. This is a classic locality and style and specimens from here are more and more hard to get. There are also several lustrous, slightly translucent, brown, Sphalerite crystals scattered over the whole display side. The piece is definitely not complete but much better in person.
