This is a stylish halo ring from the 1940's. It is a 1.87 CT Opal cabochon with flashes of predominantly red orange green and blue. It is ringed in @0.40 CTW diamonds which are well matched and bright.

The rings is size 7 and can be sized by your local jeweler. It weighs 4.3 grams and is in excellent estate condition. In my private collection for decades.
