A Wonderful Antique Vintage Australian Opal and Pearl Ring, Retro Sterling Silver, circa 1950. This beautiful estate ring holds a colorful Australian opal measuring about 7 x 9mm. This is a genuine, single cut natural opal, not a doublet or triplet. It is joined by a genuine pearl. The setting is a retro sterling silver Modernist design with imaginative detailing. Overall the ring measures about 7/16 inch long by about 3/4 inch wide from side to side. Ring Size: about 5 1/4 (could be resized by your jeweler or ask me about using mine before shipping). This ring was acquired through an estate collection and is in lovely vintage condition.
