​
South Sea cultured pearls are the most valuable of all cultured pearls.  In 1992, a strand of 23 magnificent South Sea cultured pearls set a new world record, selling at Sotheby's Auction for $2,300,000!

They are produced by the silver-lipped and gold-lipped Pinctada maxima mollusks of the Pacific and Indian Oceans off the coasts of Australia, the Philippines, Indonesia and Myanmar.

South Sea cultured pearls are larger than most other pearl types, ranging in size from 9mm to 20mm.  They can be round, drop, oval, button-shaped, baroque, or circled..

White, silver, and champagne are naturally occurring colors in South Sea cultured pearls.
