Our classic late 19th century natural robin egg blue Persian Turquoise, diamond and gold ring is of the highest quality. It was most likely made to order in Albany, NY as it comes down through a prominent family in that city. The oval turquoise cabochon, which measures 5.2mm x 7.6mm, is surrounded by an augmented halo of Round Old Cut Diamonds also accenting part of the shank and measuring between 2.5 and 2mm. The ring is unmarked, but tests for 14K, possibly up to18K. The ring will never go out of style. Whether worn on the hand or strung on a gold chain, it telegraphs the maker’s and the wearer’s dedication to excellence and an appreciation of the finest. Condition: Excellent Size: 4.5”.
