About the Mineral Aragonite


The mineral aragonite is the crystal form of calcium carbonate a chemical compound that occurs naturally in rocks most notably as limestone.  From a chemical perspective it's identical to the mineral calcite but forms under slightly different geological conditions hence has a different crystal structure.  Limestone contains both aragonite and calcite.

Aragonite can be colourless or may occur in many different colours some of which include white, grey, green, blue, violet, brown and varying shades of red and yellow.  It tends to form at low temperatures quite close to the surface of the earth and can also be found as stalactites in caves and around hot springs.  The form of aragonite that many people are familiar with are small clusters known as sputniks.  These shapes exhibit a twinned crystal habit in which the crystals radiate outwards.  This form of aragonite was named after the satelite launched by the Soviet Union in 1957 because of its shape.
