Beautiful specimen of Sphalerite and Galena. On transparent Quartz base are grown black Sphalerite tetrahedrons with superb luster. They are chunky, sharp, well isolated and shiny. Tremendous focal point is 22mm Sphalerites tetrahedron decorated by Galena cubes.  Galenas are sharp with truncated corners. They are from lustrous to matt and have gas bubbles deformations on some faces. In superb condition.

Absolutely fantastic!
