Art Deco 10.45 Carat Star Sapphire & Rose Cut Diamond Ring, French, circa 1915

Hypnotically lovely. The large, greyish blue star sapphire almost glows from within and displays a lovely, distinct asterism. Sixteen bright white rose cut diamonds surround the centre stone in a beautifully refined pierced gallery. The tri-split shoulders lead to a slim, flat shank – all in a soft, rose gold.

Accompanied by an independent jewellery report.
