Estate 18K Yellow Gold Cabochon Sapphire Diamond Rosetta Cocktail Ring 6.57ctw

A superbly crafted cocktail ring in 18-karat yellow gold, centering a 5.02-carat natural cabochon sapphire of striking depth and even royal-blue saturation. The gem’s smooth polish and internal glow evoke the finest examples of classic mid-century design. Channel-set along the shoulders are calibrated square-cut natural sapphires totaling 0.72 carat, their crisp geometry providing an elegant counterpoint to the cabochon’s rounded silhouette. Framing the centerpiece are 0.85 carat total weight of round brilliant-cut diamonds, perfectly matched in G–H color and VS2–SI1 clarity, offering refined brilliance without excess. All gemstone weights are exact and stamped within the shank. The ring weighs 9.2 grams, measures 0.60 inches from top to bottom, and is a size 6.5.
