Roseville is a bold Retro era (circa 1940) 18k yellow gold opal and diamond ring sure to make a statement! This vintage stunner centers an unusual Contra Luz Marquise Cut Cabochon opal gauged at 12.54mm x 6.70mm displaying a dreamy transparency mixed with subtle rainbow play-of-color. A marquise shaped halo of twenty-two Single Cut diamonds totaling approximately 0.40ct effortlessly surround the center opal adding a lovely sparkle to this unique ring. Roseville is finished with a simple 18k yellow gold shank that tapers slightly towards the base of the ring. It is currently a size 8.5 and can be sized to fit.
