South Sea Pearl Harvesting

Because of their long, 2-to-3 year cultivation period, South Sea pearls develop an exceptionally thick coating of nacre -- from 2 to 6 millimeters -- perhaps the thickest of all saltwater cultured pearl varieties. When extracting South Sea pearls from their oysters, technicians take special care not damage them. If the oyster is healthy, another nucleus is placed inside -- a process that may be repeated up to 4 times for a single oyster.
