Excellent and rare old specimen of bi-terminated Quartz with Boulangerite inclusions from Cavnic Mine, Romania. It displays up to 18mm colorless Quartz crystals growing in a cluster. They are very well formed and sharp with strong luster. Many of them are doubly terminated and translucent to transparent. Second generation of smaller Quartz crystals grows on the bigger ones. Black Boulangerite inclusions are seen all over. It displays on both sides. In very good condition – some small contacts.

Wonderful!
