Layman's explanation: Erythrite, also known as cobalt bloom, is a weathering product of cobalt-containing minerals such as cobaltite. Erythrite has a deep red-purple to peach or pink-red color. It is a secondary oxidized cobalt mineral that froms in monoclinic crystals, in globular, and in earthy forms. It is used as a minor ore of cobalt and as mineral specimen. This mineral is found in some mines of Ontario, Morocco, and Germany.
