Conch Pearl
A pink, non-nacreous pearl from the queen conch, prized for a flame-like surface pattern. Cannot be cultured commercially.
Conch pearls come from a sea snail in the Caribbean. They contain no nacre at all, so they have none of the usual pearl lustre.
What they have instead is a porcelain surface and a distinctive flame structure, a chatoyant shimmer that moves across the pearl like watered silk.
Colour runs from white through salmon to deep pink, with strong even pink the most valuable. They form roughly once in ten to fifteen thousand conchs.
What you will hear
“A pink pearl is a conch pearl.”
In fact: Almost every pink pearl in the market is a dyed or naturally pink freshwater pearl. Conch pearls are non-nacreous, flame-patterned, and priced in lakhs.
When you are buying
Flame is the whole point. A conch pearl without visible flame is worth a fraction of one with it, whatever the colour. Fading is a real risk, so keep them out of sunlight.
Melo Pearl
A rare orange non-nacreous pearl from the Melo melo sea snail of Southeast Asia. Flame-patterned, like a conch pearl.
Natural Pearl
A pearl that formed with no human involvement at all. Vanishingly rare, and effectively absent from the retail market.
Quahog Pearl
A purple non-nacreous pearl from the North Atlantic hard clam. Rare, and found by accident in the food trade.
Certification Labs
Independent gemmological laboratories that identify and grade stones and pearls. The name on the report is what gives it weight.
