Very well crystallized Tetrahedrites with like from a textbook shape, intergrown with Pyrite. Displays razor sharp, black, metallic Tetrahedrite tetrahedrons with strong luster. They are chunky, well isolated and shiny. Brassy, yellow and shiny Pyrites adds a nice contrast. Some Quartz crystal enrich the display. In good condition – some nicks and contacts. On acrylic base.
Superb!
