How a Tahitian pearl is formed
Aragonite, which is a kind of calcium carbonate, is secreted by the pearl oyster. This substance coats the within of the oyster shell and generates the "mother-of-pearl" lining. It also varieties the layers of the pearl. The oyster can generate aragonite secretions up to 4 instances a day with each and every secretion forming yet another layer. The layers are about one micron or 0.001mm thick. Tahitian oyster reside for about two decades which means they produce up to about two thousand layers; much more than most other pearls. The mild passes by means of these many microscopic layers and is mirrored and refracted to produce a shimmering effect. This shimmering produces superb colours which seem to be to travel and move during the pearl. This is portion of what can make the Tahitian pearl so unique.
