Produced by the silver-lipped South Sea oyster and sourced from the deep saltwater’s in Australia, these high-end pearls are extremely sensitive to the cultivation process and difficult to gather, making them both rare and expensive. Due to the large size of the oyster, South Sea pearls are the ideal choice for those looking for a larger pearl size as they typically range from 8mm-20mm. Their thick nacre and radiant, satiny luster put these pearls in a class of their own.
