Frequently asked questions
How thick is the nacre on South Sea pearls?
AAA South Sea pearls have nacre thickness of 2-6mm — by far the thickest of any cultured pearl (Tahitian 0.8-2.5mm, Akoya 0.4-0.8mm). This is why South Sea pearls have such depth of luster and why they last generations.
Are South Sea pearls a good investment?
Among gemstones, AAA-grade matched South Sea pearl strands have appreciated steadily — particularly larger sizes (13mm+) and rare overtones (deep gold, silver-blue). Tap into our wholesale program for matched-strand commissions; resale market for documented matched lots is active.
How durable are pearl rings for daily wear?
Pearls are softer than diamonds and harder gemstones (Mohs 2.5-4.5 vs diamond 10). With proper care — remove before showering, applying lotions or perfume — they last decades. We do not recommend pearl rings for activities involving manual labor or sports.
Why is 9mm a popular size in South Sea rings?
9mm sits in the most-requested band for South Sea rings — large enough to read as a statement, small enough that the price stays accessible. Each piece is graded to ensure consistency at this size.
Is white a natural color for South Sea pearls?
Yes. The white pigment is deposited naturally by the Pinctada maxima oyster as nacre forms — no dye or treatment involved. Each piece ships with certificate of authenticity noting the natural origin.
At 9mm white, these South Sea pearls represent a specific point in the Pinctada maxima harvest spectrum. 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. Solitaire, halo, three-stone, cocktail, and bypass settings in 18K gold and 925 sterling silver. Each ring features a hand-selected center pearl with high luster and minimal surface imperfections. 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 & Philippines. Ring sizing available — most pieces are 6-8 standard with custom resizing on request.
