Provenance
Original to c.1910, this blue sapphire and diamond three-stone is one of the finest Edwardian engagement rings we currently have in our collection - from the quality of the gemstones to every minute detail in the gallery, this ring is perfect.
Set to centre with a natural blue sapphire with a beautiful Mediterranean sea-blue hue and remarkable clarity. Oval-cut and claw-set in an open-back setting, flanked by two round old-cut diamonds. These diamonds are exceptionally white, of very high quality and have been perfectly matched to one another. Each hand-cut, the antique proportions and characteristic glow of old-cut diamonds make these two stones a dream to turn under light!
Further interspersed by four tiny single-cut diamonds. The gallery is intricately pierced with scalloped detail and split prong claws, above linear open-work that allows light to flood into the stones and light them up beautifully. Shoulder that are slightly open and gently taper inwards before flowing to a solid 18ct white gold band.
