It is named after the Molina de Aragon mine in Guadalajara, Spain where the gem was discovered in 1788 (the mine is situated close to the town of Aragon).
Aragonite is a unique mineral gemstone, as it has the same chemical composition also found in organic molluscs. The crystal structure of Aragonite is also very unusual in that it is often found in needle-like, six-sided prisms.
In addition to its initial discovery in Spain, three large Aragonite caves have also been discovered in Slovakia, Mexico and Argentina.
The cave in Slovakia is buried deep in the Slovak Metalliferous Mountains between Jelsava and Stitnik. Known as the Ochtinska Aragonite Cave, it was discovered in 1954 and was opened to the public in 1972. Unlike most public caves full of stalactites or stalagmites, the unusual crystal structure of Aragonite resembles small shrubs and bushes. One of the main attractions at the mine is the Milky Way Hall, where Aragonites high in the ceiling shine like the stars in the Milky Way. In gemstone terms, the Aragonite in the mine is fairly young; dating back just 13,000 to 100,000 years.
Crystal healers believe that Golden Aragonite is important to the 3rd Chakra and White Aragonite benefits the 7th. I also read Aragonite is suggested as a healer for painful knees.
