Our pearls

From the pearl farm to the finished jewel, the house selects every natural pearl one by one — for its orient, shape and character — before mounting it by hand in our Mauritius atelier.

The Tahitian black pearl

The Tahitian black pearl

Grown in the lagoons of French Polynesia, the Tahitian pearl is the only naturally dark pearl in the world. Its overtones — peacock, aubergine, sea green — exist on no other gem. Our pearls come from farms in Bora-Bora and the Tuamotu atolls, where we choose them at the source.

The Japanese Akoya pearl

The Japanese Akoya pearl

The Akoya is the pearl of absolute lustre: white, round, with an almost metallic mirror. Farmed in Japan for over a century, it is the classic pearl par excellence, ideal for refined designs.

The South Sea pearl

The South Sea pearl

Grown in Australian waters, the South Sea pearl is the largest and rarest of cultured pearls. Its thick nacre, white or golden, glows with an incomparable satin light.

Choosing well

How to choose your pearl

Lustre

The first criterion: how sharply reflections read on the pearl's surface. A mirror lustre is the mark of dense, slowly layered nacre.

Surface

The fewer the blemishes, the more precious the pearl. Perfectly clean pearls are exceedingly rare — ours are graded AAA.

Shape

Round, semi-round, oval, button or baroque: a perfect round is the most sought after, while a bold baroque makes a piece full of character.

Size

From 8 to 16 mm depending on origin: Akoya is the finest, the South Sea pearl the most imposing. Size is chosen to suit the jewel.

Hand-mounted in Mauritius

Each pearl is set in gold, white gold or silver by our artisans, piece by piece, never in series. Every creation ships with its certificate of authenticity and insured worldwide delivery.
