Art Deco 0.63 Carat Old Cut Diamond & Ruby Target Cluster Ring, circa 1925

A stunning vintage ruby and diamond ring. The old cut diamond in the centre, graded by HRD as F colour, is blindingly white and, despite the P1 clarity grading, is clean to the naked eye and impressively lively. The centre stone “floats” within a halo of twenty calibré cut pigeon blood red rubies channel set in yellow gold. The beautifully pieced gallery leads to a slim platinum shank set with six (three each side) rose cut diamonds in the shoulders.

Accompanied a diamond identification report from HRD Antwerp (#180000145867).
