A Stunning Antique Large Australian Opal Ring in 14K Yellow Gold, Estate, circa 1950's retro Art Deco - Victorian Detail. This estate ring holds a gorgeous natural single cut (not doublet or triplet) Australian Opal at center measuring about 12 x 18mm oval. This beautiful gem shows colors of fire reds, peacock greens, and hints of blues when in the light. The stone shows more color in person than can be captured in the stills. The setting is composed of 14K yellow gold and has Victorian - Art Deco style detailing. The setting was exquisitely made in China and the ring is estimated to date circa 1950's. Overall the ring measures about 15/16 inch long by about 3/4 inch wide from side to side. Ring Size: about 6 1/4 (could be resized by your jeweler or ask me about using mine before shipping). This ring was acquired through an fine estate collection and is in lovely vintage condition.
