18k Gold Two Toned Natural Blue Oval Sapphire & Diamond Estate Ring

A striking example of modern estate craftsmanship, this sculptural sapphire and diamond ring blends contemporary design with timeless luxury.

At the center sits a vibrant natural oval blue sapphire measuring approximately 6.6mm x 8.6mm and weighing an estimated 1.69 carats. The gemstone displays rich oceanic tones ranging from deep midnight blue to flashes of royal sapphire depending on lighting conditions.

The sapphire is framed by flowing architectural shoulders set with approximately 0.25 carats of near-colorless natural diamonds, adding brilliance without overpowering the center stone.

Distinctive yellow gold bezel-set accent diamonds create subtle contrast against the white metal mounting, giving the piece depth and designer character.

Likely dating to the early 2000s designer estate period, this ring reflects the era’s shift toward sculptural silhouettes and mixed metal artistry.

Perfect as a statement ring, alternative engagement ring, or luxury sapphire collector piece.
