Aragonite

Aragonite – calcium carbonate – can crystallize in various crystal structures. Calcite, marble and lime generally occur in the form of calcite. In nature, aragonite is formed, for example, in mussel shells and pearls and corals. Most often, aragonite is strongly colored by small amounts of metal salts. Pure white aragonite is only difficult to obtain. Aragonite is usually opaque, milky, white. Aragonite is used as a substrate for the precipitation of If you add dyes, you get particularly colorful aggregates.
