"Limonitic matrix, the top mostly coated by bubbly micro crystalline brilliant green Conichalcite. There are small partial crystals and crystalline colorless translucent calcite scattered about. Very rich for this species and an attractive cabinet piece! Conichalcite has a sparkling grass green color that once observed is hard to mistake for any other mineral. It is often encrusted onto limonitic rocks that have a red to yellow color and the two produce a very colorful specimen. Conichalcite forms in the oxidation zone of copper ore bodies. Oxygen rich ground water that might react with copper sulfide and/or copper oxide minerals produce a wonderful assortment of attractive and colorful minerals in a zone called the oxidation zone. Conichalcite is just one of these minerals. " Location: Ojuela Mine, Mapimi, Durango, Mexico
