  • Level 450/500, Block 22
  • Kruchev Dol Mine, Madan
    Bulgaria
  • A plate of galena crystals from this modern day, classic locality. It is difficult to see but his is, in fact, one big spinel law twin and that is why the crystals appear to be in parallel. On one side, the crystals have that rounded appearance that we sometimes see from Madan. Just partially. The rest of the crystals are exceedingly sharp! Excellent luster. Very nice piece.

  • Radvanice
  • Katerina Coal Mine
    Czech Republic
  • These unusual iridescent galena specimens are exhalative formations that come from a, no longer operational, coal mine with a burning waste dump. The galena crystals form at a temperature of more than 600C. They are slightly radioactive (not nearly enough to cause harm). The specimens come with a handwritten label from a dealer based in the Czech Republic.
