A stunning and unusual geometric cocktail ring from circa 1935, bridging late Art Deco and Retro design with bold, impeccably executed volumetric architecture in solid 18K white gold (tested) and a high-polish finish. Defined by sharp rectilinear angles balanced with circular curves, the ring is finished with refined millegrain detailing throughout the diamond settings. At the center sits a round European-cut diamond weighing approximately 0.95 carat (G/H color, SI1 clarity), surrounded by 56 European-cut round diamonds in flush millegrain settings totaling approximately 1.16 carats (F/G color, VS2 clarity), and accented by four bezel-set round cabochon natural blue sapphires totaling approximately 0.43 carat. The ring weighs a substantial 21.95 grams, measures 33 x 22mm, rises 11mm off the finger, and is currently size 8.5 (sizable). Accompanied by a presentation jewelry box, it remains in excellent condition with only minimal wear and all stones secure. Very good conditions. All our diamonds and colored gemstones are naturally earth-mined. Any synthetic (lab-grown) stones will be clearly indicated in the description. Upon Request, Auction House may provide Ring resizing or/and appraisal. This will carry an additional cost. Appraisals are made by our in house GIA certified Gemologist.
