A Gorgeous Antique Australian Opal and Sapphire Ring, Retro Art Decom circa 1940-50's Era with Heart Shaped Opal. This beautiful antique ring holds a genuine Australian opal at center in a 6mm heart shaped cut. The opal displays colors of red, greens, and blues in the light. The opal is a genuine, single cut stone, not a doublet or triplet. It is surrounded by deep rich blue sapphires. The setting is yellow gold and done in a retro Art Deco style. Overall the ring measures about 7/16 inch long by about 3/4 inch wide from side to side. Ring Size: about 6 1/2 (could be resized by your jeweler or ask me about using mine before shipping). This piece was acquired through an estate collection and is in lovely vintage condition.
