South Sea pearls are produced in White lipped, Silver lipped and Gold lipped oysters or Pinctada Maxima, One of the largest pearl bearing oysters in the world, hence the maxima part of their name! The oyster shell hosts can be as large as 12 inches across, they inhabit the waters of Australia, New Guinea, the Philippines, Indonesia and Burma.

These oysters produce pearls whose nacre is coloured according to the mother of pearl coloration of its host shell, so white and silver lipped oysters birth pearls that are mainly strong white in colour with a range of overtones that range from silver to pale pink and green, or any combination of these. Whereas gold lipped oysters will create pearls that go from a warm creamy white to a deep orange gold hue, through a stunning light creamy gold hue, there are often green and peach overtones.

Tahitian pearls grow in the Pinctada Margaritifera otherwise called the Black lipped oyster which produces black pigment and are found in the surrounding area of the archipelago of French Polynesia, Panama and Mexico. The colours of Tahitian pearls are naturally dark and normally range from grey to black and peacock green to aubergine; however, they can sometimes be very unusual colours like white with grey overtones, gold, copper, pistachio green, sky blue and pink, there is one clue to spotting if a pearl is created in a black lipped oyster and that is … a grey overtone.
