A beautiful colorful Oscar Heyman cocktail ring, created in New York City (circa 1970–1980) and designed as an iconic Yin-Yang ballerina form in solid 18k yellow gold and platinum with a high-polished finish. Richly set with 35 natural earth-mined gemstones, the design balances vivid Colombian green emeralds with crisp white diamonds in a striking alternating pattern. At the top, an oval brilliant-cut diamond measuring 7 x 5 x 4 mm and weighing approximately 0.60 carats (E/F color, VS1 clarity) is secured in a four-prong setting, surrounded by 17 tapered baguette-cut diamonds totaling approximately 1.24 carats (E/F color, VS1 clarity) and 17 tapered baguette-cut natural vivid green Colombian emeralds totaling approximately 1.38 carats, all in flush-prong settings. The ring weighs 6.20 g (3.98 dwt), is size 6 (resizable upon request), measures 19 x 20 mm (0.47 x 0.79 in), and rises approximately 10 mm over the finger. Stamped with maker's logo, serial numbers, and assay/warranty marks for 18k gold and platinum, and signed "HB 18K PLAT 18123." 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.
