The Bain-de-Marie Grande Ring, named after the gentle French cooking technique, is one of Luminous 27’s most iconic pieces. Defined by its sculptural bombé silhouette, each ring is hand-carved from natural semi-precious stone with meticulous attention to detail. Finished with an 18K yellow or white gold interior and our signature gold drop, the piece balances softness, volume and form. Originally conceived as a singular jewel, the Bain-de-Marie Grande Ring can also be stacked with other bombé rings or worn as a pendant with our 60 cm or 90 cm rollo chain. Each stone is hand-selected and naturally unique; variations in colour are to be expected and celebrated. Please allow approximately 1–3 weeks for shipment, as all Luminous 27 fine jewellery pieces are made to order.
