This lot contains six natural Pyrite specimens displaying strong metallic luster and attractive rainbow surface coloration. The specimens show well-developed crystal formations and natural cubic crystal habits typical of pyrite mineralization. Several pieces display iridescent rainbow surface oxidation, producing gold, copper, and multicolored reflections across the crystal surfaces. These colors are a natural surface effect commonly seen in pyrite specimens. The specimens vary in shape and crystal structure, making the lot visually appealing for mineral collectors, display purposes, or educational collections. Please review all photos carefully, as they form part of the description.
