These bivalves are the largest pearl oysters in the world. They have a very strong inner shell layer composed of nacre, also known as "mother of pearl". They are important in the cultured pearl industry as they are used to produce South Sea pearls.

Known also as the South Sea Pearl or Philippine Pearl, it was declared by Philippine President Fidel Ramos as the national gem in 1996 through Proclamation No. 905. This is also featured at the reverse side of the Philippine 1,000-peso bill.

Description

Pinctada maxima Pinctada maxima Wikipedia

Pinctada maxima oysters grow very large, up to 12 in (30 cm) in diameter. The two color varieties have different coloration in the outer edge of the interior. This mother of pearl or nacre is responsible for the color of the pearls that the oyster can produce. Water temperature, plankton and sediments determine which color variety is more common in a given area.

Pearl farming (Perliculture)

Pinctada maxima produces South Sea pearls in colours ranging from white, silver, champagne, gold. Pinctada margaritifera produces South Sea pearls commonly referred to as Tahitian pearls or black pearls which in fact come in colour hues including grey, platinum, charcoal, aubergine, peacock. Currently south sea pearls are cultured primarily in Australia, Indonesia, Tahiti and now, the Philippines. Because these pearl oysters are so large, a much larger nucleus than usual can be used in culturing. Commercial pearl farming in Australia is mostly centred around the coastal waters of Broome, 17.9614 degrees South and 122.2359 degrees East, located in the Kimberley region of Western Australia. Best known and valued for their white/silver with pink hues from the silver-lipped pearl oyster, Australian South Sea Pearls can grow beyond 18mm - 20mm in diameter, with a typical size of 10mm - 13mm when harvested following a two-year gestation. South Sea pearls farmed in the Philippines, typically produce golden pearls from the gold-lipped pearl oyster, which are currently experiencing a surge in popularity, resulting in increased market-demand, particularly in China. The Tahitian or black pearl comes from the black-lipped pearl oyster, produced from the waters surrounding Tahiti and the French Polynesian archipelago.
