Platinum Diamond and Sapphire Toi et Moi Ring by Oscar Heyman

A magnificent platinum toi et moi ring by Oscar Heyman featuring two round brilliant cut diamonds in a dramatic bypass design, framed by sweeping fans of calibré-cut blue sapphires and tapered baguette diamonds. The design is a masterclass in mid-century American fine jewellery craftsmanship.

The two centre diamonds sit in four-claw settings, each surrounded by arcing sprays of custom-cut sapphires that fan outward in opposing directions, creating the distinctive toi et moi silhouette. The sapphires are precisely calibrated tapered baguettes, individually fitted to follow the curve of the design. Additional tapered baguette diamonds mirror the sapphire fans on the opposing sides, with small round brilliant accents at the junction points.
