Calcite with Chalcopyrite - near Chenzhou, Hunan, China 💎sold 💎 Bright bursts of iridescent chalcopyrite form in the center of thin wafers of calcite, like psychedelic frogs on lily pads. On a crystalline level, the specific formation of calcite attracted chalcopyrite molecules to their centers, forming these crazy pebble-looking nugget things... though some of the chalcopyrite clusters are found nestled in crevices as well. The concept of attraction to crystal edges/centers is similar to the
