Large and luminous White South Sea pearls from Australia and the Philippines are the largest and rarest of all cultured pearl types in the world. Pearls cultured in the Pinctada Maxima saltwater oyster, which can grow up to a foot in diameter at maturation, routinely obtain sizes that range from 9.00mm up to an astonishing 21.0mm! The pearls golden and white colors are completely natural, needing no dyes or artificial enhancements.

Cultured South Sea pearls are also known for their soft, satiny glow which is due to their thick nacre layers acquired through as much as 4 years' cultivation time.
