A Gorgeous Antique Australian Opal and Mine Diamond Ring Wedding Vintage Victorian , 19th Century. This beautiful ring dates to the late 19th Century and is composed of Victorian silver. The center of the ring holds a stunning natural antique Australian Opal and it is joined by two antique mine diamonds on the sides. The opal measures about 3 x 4mm oval. The setting has lovely period detailing around the gems. This ring measures about 1/4 inch long by about 11/16 inch wide from side to side. Ring Size: about 7 (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 with a few nicks on the edge of the opal near the bezel found under 10x magnification and mentioned for accuracy. These antique opal and diamond rings are becoming scarce and this is a beautiful classic example.
