Thank you for submitting your item for appraisal. This appears to be a vintage 14 Karat Gold domed opal cabochon cluster cocktail ring, approx. 2.00 CTW round cabochon opals. Similar cocktail rings have been offered and sold at auction, apparently they are most appreciated in the country of origin. The estimate is based on similar cocktail rings offered or sold at auction. "Asking prices" in the right retail environment can be higher and vary.
