White Aragonite Mineral
Aragonite is a calcium carbonate mineral with the same chemical formula as calcite but with a different crystal structure. It occurs in several colours and is formed at low temperatures close to the surface of the earth, in caves as stalactites and around hot springs.
It was first named in 1797 after the village of Molina de Aragón in Spain and some of the finest specimens still come from there. Aragonite is the main component of coral, pearl and the shells of many marine molluscs.
This is quite a unique piece of white aragonite and most of this mineral that you see being offered for sale tends to be in shapes known as sputniks which are orange coloured crystal clusters made up of multiple twin crystals.
This white aragonite crystal formation is slightly translucent and exhibits a vitreous lustre. It's important to note that unlike calcite it is soft and brittle so must be handled with care. On Mohs scale of mineral hardness it grades just 3½ to 4.
