Edwardian 10.44 Carat Natural Ceylon Sapphire & Old Cut Diamond Cluster Ring, circa 1905

The most perfect blue. This glowing cornflower Ceylon sapphire – natural, unheated – is claw-set above a surround of eighteen high white and bright old cut diamonds. The finely hand-pierced gallery leads to a split shoulder shank with an over-sized central leaf to a channel yellow gold shank. Hugely impressive.

Accompanied by a sapphire report from Gemmological Certification Services (GCS) stating the sapphire shows no indication of heating, and is Sri Lankan (Ceylon) in origin.
