South Sea pearls are among the largest commercially harvested cultured pearls in the world. The average size of a South Sea pearl is 13mm, with most harvests producing a range of sizes from 9mm up to 20mm.

The South Seas lie between the northern coast of Australia and the southern coast of China. These waters are the native habitat of the large oyster, the Pinctada maxima. This oyster grows up to 12 inches in diameter, and can be nucleated with a much larger bead than other saltwater oysters such as the Akoya.

There are two varieties of Pinctada maxima: the silver-lipped and the gold-lipped. The two are distinguished by the coloration of the outer edge of the interior. This shell is also known as mother of pearl, and is responsible for the coloration of the cultured pearls produced.
