Aragonite, the pseudomorph of calcite, diameter 6,9 cm

Close Relationship with Calcite

Aragonite and calcite are essentially related, as aragonite is a polymorph of calcite. This means they have the same chemical formula but are in different phases. Aragonite is named after the Spanish location 'Aragon', where the mineral was first discovered. It has the unique property of easily incorporating other minerals, resulting in an almost unlimited range of colors. This makes each aragonite crystal unique and special.

Origin and Structure of Aragonite

Aragonite is a carbonate mineral and one of the three most common crystal forms of calcium carbonate (CaCO3), the others being calcite and vaterite. It is formed by biological and physical processes, including precipitation from marine and freshwater environments. The crystal structure of aragonite differs from that of calcite, resulting in an orthorhombic crystal system.

Sources and Use

Aragonite was first discovered in Molina de Aragón in the province of Guadalajara in Castilla-La Mancha, Spain. In aquariums, aragonite is considered an essential component for replicating reef conditions. Aragonite provides the material needed for many marine life and also keeps the pH of the water close to its natural level.
