Calcite with Chalcopyrite
Out of stock
A classic example of the material that has been produced from the Milliken (Sweetwater) complex in the Viburnum Trend over the years. This one came from an older collection, so not newer production. The prismatic crystals reach 4cm and are set on a plate of dolostone and iridescent chalcopyrite. One crystal broken at the bottom can likely be trimmed off.
Locality: Milliken Mine, Viburnum Trend, Reynolds County, Missouri
Composition: calcium carbonate
