Impressive specimen of mirror lustrous Spinel Law twin Galena with Sphalerite, Quartz and Calcite. It displays sharp, well formed superb flat faces Galena twins with excellent brilliance and light reflection. They are vertically crystallized parallel rosettes surrounding a Sphalerite core. The spinel twins are thin stepped plates, staggered one after another with like tooled tips. Black lustrous Sphalerites tetrahedrons with truncated tips enrich the display. Some Quartz crystals and Calcite are seen too. In excellent condition – some outside edges contacts.

Wonderful!
