This is an exceptional estate ring featuring natural diamonds and stunning blue sapphires. The diamonds are high-quality, natural, clean, and well-cut, measuring approximately 2.3mm and 2.15mm. The blue sapphires are remarkable; under magnification, I can see a few minor inclusions, suggesting they are natural sapphires, though I cannot confirm with absolute certainty. I had them tested and they tested as sapphires. The setting measures just under 1/2 inch from end to end, and the total weight is 2.7 grams. Very well made high quality, heirloom piece. I had this polished by my jeweler, so it's in great condition.
