Iridescent Chalcopyrite on Calcite from Fengjiashan Mine (Daye Copper Mine)
Dimension: 5.8cm x 3.7cm x 1.9cm
Locality: Fengjiashan Mine (Daye copper mine), Daye Co., Huangshi, Hubei, China
This is an old time materials acquired by my father in around 2000. Striking, iridescent Chalcopyrite crystals almost completely covered the Calcite crystals grown underneath. They look like a plate of armor worn to protect the Calcite, so interesting! There is a good isolation between the Calcite crystals and the Chalcopyrite are highly crystalized. The iridescence is in a metallic color ranges from red, orange to yellow which is in lovely contrast to the white Calcite crystals! And the Calcite exhibit a medium red fluorescence under UV lighting 365nm. No more of this style have been found since, they are definitely rare and desirable. Comes with a high quality copper-wired display stand.
