AC Silver has dated this Art Deco Sapphire Ring to the 1920s.
This stunning, fine and impressive antique sapphire engagement ring has been crafted in platinum.
The cluster design displays a feature millegrain decorated collet set 1.50ct cushion cut Basaltic blue sapphire to the centre of the design.
The sapphire is encircled by twelve individually collet set Old European round cut diamonds, totalling 1.15ct, comprising a scalloped halo border.
The pierced decorated ring shoulders integrate with the main setting and blend seamlessly with the plain hallmarked ring shank.
The ring shank is hallmarked to the outer surface with the French platinum mark (dog's head) and the ring has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as platinum.
This impressive cushion cut sapphire cluster ring is supplied with an IDGL diamond and gemstone grading report card, in addition to a sapphire report card and certificate supplied by the Gemmological Certification Services, London*.
Such original antique French examples set with a stunning untreated basaltic sapphire, in addition to bearing clear hallmarks, are becoming increasingly difficult to locate.
This sapphire cluster ring with Old European diamonds combines intense gemstone colour with period diamond cutting to create a design of enduring elegance. The central sapphire provides rich visual depth, while the surrounding Old European cut diamonds produce a softer, broader brilliance characteristic of hand-cut antique stones. The cluster arrangement enhances perceived scale and symmetry, making the ring particularly suited to anniversaries, engagements and other significant occasions. Its antique craftsmanship and timeless design also give it strong heirloom and collector appeal.
NOTE: * This documentation accredits the sapphire originating in Basaltic deposit and certifies that the gemstone shows no indications of heating.
