This is a gorgeous 18K yellow gold piece, circa 1970s. The design looks like Oscar Heyman's famous swirl creation. But it is not stamped with Oscar Heyman mark. The workmanship and quality of stones are very fine, as it would be in a designer piece. The center genuine ruby is simply incredible, extremely brilliant and the bursting red color just jumps at you. Great ruby gem!! It measures (6.4mm x 4.8mm) oval cut and estimated to be .65 carat. There are 18 additional rubies graduating in size, total round ruby weight is estimated to be 1 carat. The diamonds are graduating in size also. These are VS-1-2 in clarity, GH in color, total diamond weight is estimated to be 1 carat. Fantastic diamonds, very well cut! Ring size 6.25 (sizable), the weight is 7.5 grams. The presentation is 18.29mm tall (3/4") and is raised 12mm high from your finger.
Outstanding quality! Most likely Burmese rubies!
