Art Deco 0.51 Carat Old Cut Diamond Engagement Ring, circa 1920

A stunning antique diamond ring. The old European cut diamond in the centre – graded by HRD Antwerp as H colour, SI1 clarity – is burstingly white and lively. The stone is secured in a four-claw square platinum collet, with finely milgrained and beaded shoulders, leading to a slim, D-shaped platinum shank. Exceptionally pretty.

Accompanied by a diamond identification report from HRD (#180000145832).
