A beautiful specimen of bedazzling galena cubes with sphalerite tetrahedrons, quartz and calcite from the famous Madan ore field, Bulgaria. It displays razor sharp galena cubic crystals to 17mm. They are strongly mirror lustrous and light reflective. On the faces are seen gas bubble deformations. Black sphalerite tetrahedrons grow among the galena. Spiky quartz crystals and calcite are seen too. It shows attractively all over 360 degree. In very good condition – some small damages.

Fantastic!
