What is a Tahitian pearl?

Definition
Tahitian pearls are cultured saltwater pearls produced by the black-lipped oyster Pinctada margaritifera, farmed primarily around the islands of French Polynesia, particularly the Tuamotu Archipelago near Tahiti. They are the only pearls that grow naturally in dark colours, ranging from charcoal and black through deep greens, purples and an especially prized peacock colour that combines green and rose overtones. They are larger than Akoya pearls, typically 8 to 14 millimetres, with thick nacre that gives them a deep, rich lustre.
Frequently asked questions
- Are Tahitian pearls real pearls?
- Yes, Tahitian pearls are genuine cultured pearls, grown by live oysters with a bead nucleus introduced to stimulate nacre production. The dark colour is entirely natural, produced by the pigments in the oyster's mantle tissue, and no dyeing is involved in quality Tahitian pearls.
- What makes the peacock colour so valuable in Tahitian pearls?
- Peacock is considered the most desirable Tahitian pearl colour because it combines a dark green base with a distinct rose or pink overtone, creating a complex, shifting iridescence. It is relatively uncommon even within the Tahitian range, which is why peacock-coloured strands command a premium.
- How do Tahitian pearls compare to black Akoya pearls?
- Black Akoya pearls are dyed, while Tahitian pearls are naturally dark, which is a significant difference in quality terms. Tahitians are also substantially larger and have a different lustre character, a deeper, softer glow rather than the mirror-bright shine of Akoya. Natural colour is always preferable to dyed when comparing value.
