Captivating at first glance and intoxicating at every turn! The longer you look at this breathtaking beauty, the more you find to fawn over– the world-class opal, its gorgeous sapphire halo, the diamond-studded deco mounting– this is a cocktail ring for the ages! Handmade in platinum in the roaring 1920s, this art deco setting features about half a carat of baguette cut and round single cut diamonds on its shoulders. They lead up to an epic halo of fourteen .25 carat true blue Ceylon sapphires, totaling around 3.50 carats. This halo spotlights the lead in this star-studded spectacular of a ring–a 7 to 8 carat fine semi-black opal from Australia's famed Lightning Ridge mines! This top-quality opal is covered in neon bursts of every color on the spectrum, flashing as it moves in the light amidst the glittering sapphires and diamonds. This knock-out has an appraisal value of around $6.5k that does not take into account its antiquity or the labor it would take to hand-make this ring as it is in platinum. We are proud, as always, to offer it at the most reasonable price imaginable. The ring is currently a size 8 1/4 and may be easily resized upon request. The top measures about 7/8 inch in diameter.
