What is the difference between chalcopyrite and pyrite?

While both minerals have a metallic yellow appearance, chalcopyrite is often softer and features more irregular crystal structures compared to the distinct cubic shapes frequently found in pyrite. Additionally, chalcopyrite often displays colorful iridescent tarnishing that pyrite typically lacks.

Are these specimens treated with any chemicals?

These chalcopyrite specimens are provided in their raw, untreated state. This ensures that the metallic reflections and textures you see are the result of natural geological processes rather than artificial enhancements.

How should I care for my chalcopyrite specimens?

To maintain the appearance of your minerals, keep them in a dry environment. You can gently remove dust with a soft, dry cloth. Avoid using harsh chemicals or prolonged exposure to moisture, as this can alter the natural surface of the mineral over time.
