This exquisite miniature-sized cluster of chalcopyrite from Bulgaria exhibits vivid metallic iridescence in deep blue to violet-purple tones, creating a captivating visual effect across its crystalline surfaces. The layered, micro-textured crystal habit enhances the interaction with light, producing shifting hues that seem to glow with a subtle internal fire as the piece is turned in hand.

Specimens like this are prized for their vibrant patina, which results from natural oxidation processes that form a thin interference layer over the chalcopyrite surface. This results in the unique play of colors that makes iridescent chalcopyrite highly collectible—particularly when the coloration is as saturated and uniform as seen here.

Aesthetically balanced and display-ready, this piece is a wonderful example of the colorful metallic mineral material that Bulgaria is known for. Ideal for collectors of miniature-sized metallic species or anyone who appreciates the optical drama of iridescent sulfides.
