A bold, architectural band from Mauboussin, the storied Place Vendôme house. A square cluster of round brilliant diamonds sits center stage, flanked by inlaid mother-of-pearl shoulders with soft silver overtones that catch the light as the hand moves. The wide, flat-topped profile gives the ring real presence on the finger while keeping the design clean and geometric rather than ornate.

Fully signed and numbered inside the shank, with the French eagle head guarantee mark for 18k gold confirming both authenticity and metal content. A striking, wearable piece from a house whose history runs alongside Cartier and Van Cleef & Arpels.
