Edwardian Three-Stone Sapphire & Diamond 18ct Gold Ring

A beautifully crafted Edwardian sapphire and diamond ring, set in 18ct gold and bearing the maker’s mark of British jewellers Constantine & Floyd Ltd. The ring features three antique oval-cut natural sapphires totalling approximately 1.66 carats, arranged in a graduated three-stone design. The sapphires display a rich, vibrant blue and are separated by four old-mine-cut diamonds totalling approximately 0.20 carats. The contrasting white diamond settings enhance their brightness, while the finely detailed pierced and carved gold shoulders are particularly characteristic of the period. Beautifully preserved in excellent condition, this is a fine example of Edwardian craftsmanship, combining strong sapphire colour with delicate period detailing. Its balanced proportions would make it a distinctive antique engagement ring or an elegant dress ring.
