Object Description

A stunning, fine and impressive antique 4.50 carat sapphire and 1.46 carat diamond, 18 carat yellow gold cluster ring/brooch; part of our diverse antique jewellery and estate jewelry collections.

This stunning, fine and impressive antique sapphire cluster ring/brooch has been crafted in 18ct yellow gold.

The pierced decorated, cluster design is ornamented with a stunning central feature claw set oval cut 4.50ct blue sapphire.

The sapphire is surrounded by sixteen impressive individually claw set Old European round cut diamonds, totalling 1.46cts.

The plain ring shoulders integrate with the lower portion of the setting and blend seemlessly with the shank.

This versatile piece of antique jewellery may also be worn as a sapphire brooch via a screw fitment to the reverse of the central cluster design; this is a rare and highly desirable configuration.

The original 18ct yellow gold bar brooch frame has a central screw fitment, flanked with trifurcating strands enveloped with a cuff design to a fleur-de-lis style terminal to either end.

This yellow gold antique sapphire ring/brooch is supplied with an independent diamond grading report card, in addition to a sapphire report and certificate* supplied by the Gemmological Certification Services, London.

NOTE: * This documentation certifies that the gemstone shows no indications of heating; non-heated sapphires are a scarcity.
