Madama is a trade nomenclature term used in the Tahitian and South Sea cultured pearl markets to describe pearls that are predominantly circled or ringed in form but otherwise of high lustre, clean nacre and good colour. The term has French and Polynesian origins, reflecting the Francophone administrative history of French Polynesia, where the bulk of Tahitian pearl culture is carried out, and is most often heard in producer-side and Hong Kong dealer language rather than in formal laboratory grading reports.

Position in the grading hierarchy

The standard Tahitian pearl grading system used by Tahiti's Direction des Ressources Marines and adopted in modified form by major dealers runs from A or Top Gem through B, C and D, with shape categories spanning round, semi-round, drop, button, oval, baroque and circled. Madama sits as a sub-category description that recognises that a circled pearl with strong lustre and clean surface can outshine a round pearl of weaker lustre and is therefore commercially desirable in its own right, particularly for designers seeking distinctive single-pearl pendants and earrings.

Different dealers and producers apply the term in different ways: some restrict it to circled pearls of A grade or better, others use it more loosely. Because the term lacks an internationally codified definition, buyers should request the specific quality criteria a vendor applies before relying on the label alone. CIBJO's Pearl Book and the GIA cultured pearl description system both describe circled and ringed pearls in formal terms, but neither codifies madama as a standardised grade.

Trade context

Madama-tier pearls are a meaningful share of high-end circled Tahitian production and offer a distinctive aesthetic for designers willing to work with pronounced surface ringing rather than pure round shape.
