Not every pearl is grown to plan. Keshi pearls are one of the few genuinely accidental treasures in pearling, formed by chance rather than design, and prized for exactly that reason.
How Keshi Pearls Are Formed
When a South Sea pearl is cultured, a small nucleus is inserted into the oyster to begin the growing process. Occasionally, the oyster rejects that nucleus but retains the surrounding tissue, which continues to secrete nacre on its own. The result, months or years later, is a Keshi pearl: solid nacre from centre to surface, with no bead at its core.
What Makes Keshi Pearls Different
Because they're 100% nacre with no nucleus, Keshi pearls often have an especially deep, almost molten lustre. They're also naturally irregular, no two are alike, ranging from near-round to distinctly baroque, which gives each piece a one-of-a-kind character that's hard to replicate in a nucleated pearl.
Are Keshi Pearls Valuable?
Keshi pearls are graded on the same qualities as any South Sea pearl, using the AUTORE Five S’s™ system. Because they can't be predicted, fine Keshi pearls are genuinely rare, though their smaller average size compared to classic round South Sea pearls typically makes them a more accessible entry point into South Sea pearl jewellery.
How to Style Keshi Pearls
Their irregular, textural shape makes Keshi pearls especially versatile, layered on a fine chain, scattered through a strand with gemstone beads, or set as a single statement drop. They pair beautifully with both delicate everyday pieces and bolder, stacked looks.
Frequently Asked Questions
