Rare Iridescent Chalcopyrite | Sweetwater Mine
Iridescent Chalcopyrite on Calcite | Sweetwater Mine, Missouri
A vivid iridescent chalcopyrite specimen from the Sweetwater Mine in Reynolds County, Missouri.
The surface is densely coated in micro-crystalline chalcopyrite displaying intense natural flashes of electric blue, violet, magenta, and gold. The color shift is dramatic and metallic, changing under movement and directional light. Beneath the iridescence, the textured calcite matrix forms the characteristic layered ādragon scaleā structure associated with this locality.
Sweetwater material is increasingly scarce due to restricted access to the mine, making well-covered specimens highly sought after by collectors.
