A stunning, fine and impressive antique 1.77 carat natural blue Basaltic sapphire and 1.86 carat diamond, platinum marquise shape ring; part of our antique jewellery collections

SKU A4309

This stunning, fine and impressive antique sapphire and diamond ring has been crafted in platinum.

The marquise shaped mount is ornamented with three collet set oval mixed cut natural blue Basaltic sapphires displayed in a vertical formation to the centre of the design.

Sixteen mixed collet set Old European round cut and eight-cut diamonds embellish the border, with a further four collet set eight-cut diamonds completing the arrangement.

The subtly flared pierced decorated ring shoulders blend seamlessly with the plain hallmarked ring shank.

This stunning 1920's antique diamond cluster ring is hallmarked to the interior of the shank with the marks for platinum (10% irid platinum*).

This fine dress ring is supplied with an IDGL diamond grading report card**.

NOTE * Any platinum alloy has to state the alloy metal first eg iridium 10% - platinum 90% in this instance.

** The Gemmological Certification Services (GCS) lab has verbally accredited the sapphire originating in Basaltic deposits and verifies that the gemstone shows no indications of heating; non-heated sapphires are a scarcity.
