1.11 ct Diamond and 0.83 ct Sapphire, Platinum Trilogy Ring - Vintage Circa 1980


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

The pierced decorated setting displays a feature 1.11 ct princess cut diamond four claw set in relief to the centre of the arrangement.

The diamond is flanked on either side by an individually four claw set square cut Basaltic blue sapphire.

The ring shoulders are accented with a subtle lobed cuff design and blend seamlessly with the plain hallmarked ring shank.

The sapphire and diamond engagement ring is hallmarked to the interior of the shank with the platinum fineness mark (plat and 950).

This vintage 1980s dress ring is supplied with an independent diamond grading certificate for the feature diamond in addition to an independent diamond grading report card for the sapphires*.

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