The pieces in this collection are hand-graded against the AAA-AA-A scale: surface clean to 95%+ for AAA, 85%+ for AA, with mirror luster the defining marker of AAA. Single pearls and wholesale lots for custom jewelers, designers, and pearl collectors. Drilled or undrilled on request. Hand-graded per the AAA-AA-A scale. South Sea pearls are the largest commercially-cultured saltwater pearls (9-20mm). Golden South Sea command 30-50% premium over white at the same size. Sourcing: direct from oyster farms in Australia, Indonesia \u0026amp; Philippines.
