Description

Sharply terminated chalcopyrite from an old collection, bought in Baia Mare in 1968 (collection card). The crystals reach a size of 2.7 cm. What’s extraordinary about this piece are the amazing metallic iridescent patina with violet, red and blue shades. Bright dolomites give a good contrast to the intense colors. Very impressive in real life!
