Extremely shiny and lustrous Galena crystals decorated by twinned Sphalerite. The Galena crystals are mirror lustrous and light reflective. They have very sharp geometry of the crystals and perfect penetration twinning. Some cubes have truncated corners. Superb  crystals of black and sharp Sphalerite octahedrons grow above. They have superb twinning and some gemminess. In very good condition – some small nicks and side contacts.
Bedazzling!
