Art Deco 1.10 Carat Old Cut Diamond Engagement Ring, French, circa 1925

Item #: 9546S149.

A wonderfully pretty antique diamond engagement ring. The old mine cut in the centre – graded by HRD as H colour, SI2 clarity – is impressively white and bright. This scintillating diamond is secured in an eight-claw platinum collet with an open gallery above a scalloped back plate, allowing plenty of light into the stone. Intricate scroll detailing in the gallery leads to tapering white gold shank, with each shoulder set with three rose cut diamonds.

Accompanied a diamond grading report from HRD Antwerp (#180000034590).
