The South Sea Pearl Blog / cultured pearls

Compare South Sea, Tahitian, and Akoya cultured pearls by oyster species, appearance, size tendency, luster, matching, and jewelry use—without assuming that one type is universally superior.

Pearl pairs are judged across size, shape, color, luster, surface, and orientation. This guide explains the practical matching sequence, acceptable natural variation, and the difference between measured similarity and convincing visual balance.

Learn how routine pearl processing differs from color and surface treatments, what natural-color claims mean, and how seller disclosure and independent laboratory reports answer different questions.

Cultured pearls are real pearls grown inside living oysters — “cultured” has never meant fake. What the word covers, how the three saltwater families differ, and how to judge a piece before you buy.
