A 10k yellow gold natural opal ring from the 1930s 1940s. This size 6 ring features a fancy 3/4 x 1/2" setting holding a natural cushion cut style 3/8 x 5/16" opal with pink, green and blue fire. This ring is stamped 10K with a crowned M maker's mark. It weighs 2.2 grams and it is in very good condition with no cracks, dents, bends, corrosion, damage or repairs however there is a shallow corner chip and a patina of wear to the bezel-set opal's face which somewhat clouds the underlying flash of the stone. The stone can easily be repolished, bringing out the colours, and the chip can be smoothed out. All items are thoroughly and conservatively graded and all condition issues are noted; all items are vintage or antique and may have slight signs of gentle use.
