Marvelous specimen of Chalcopyrite slightly iridescent when properly lighted from the famous Madan ore field, Bulgaria. The Chalcopyrite crystals are yellow colored, lustrous and strongly light reflective. They are well shaped with attractive striations. Shiny cubic Galena crystals grow atop. Displays attractively all over 360 degree. In very good condition – one partial base part crack. On acrylic base.

Splendid!
