"The limonite matrix here is laced with pockets richly coated with pretty green conichalcite, which is actually very lustrous little botryoidal blooms looked at closely. 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: Mina Ojuela, Mapimi, Durango, Mexico
