A single oval natural sapphire in deep Royal Blue, held by four slim claws in polished 18K white gold, sits at the centre of a delicate openwork band. Along each shoulder, milgrain-edged marquise frames set with diamonds alternate with tiny round sapphires, like a fine line of vintage lace.
Porte-bonheur is French for a small charm of good luck. A 0.5 carat eye-clean natural sapphire with South African full-cut diamonds on a slim polished band — a quiet proposal ring, an everyday keepsake, and a lasting September birthstone gift.
