16.40 Carat No-Heat Cabochon Sapphire and Diamond Edwardian Ring
Phenomenal old gem material, transformed into a truly magnificent bullet-shape (or ‘sugarloaf’) cabochon, is showcased in a sublime Edwardian mounting, circa 1900. This impressive, collectible and mesmerizing 15.75 carat natural, no-heat sapphire is graced with a delicate halo of fine European-cut diamonds. The sapphire is almost flawless and displays the rich blue glow and internal characteristics one would expect in an ultra-fine Burmese gem; in fact, here's what the AGL (American Gemological Laboratories has to say: "Although this material exhibits certain visual and internal characteristics associated with Burma (Myanmar), it is the opinion of the laboratory, based on the weight weight of evidence, that the origin would be classified as Ceylon (Sri Lanka). An absolutely sensational antique ring from all perspectives! Ring is a size 5.
