Sterling Silver Ring hand made in Peru. There is a large Oval bezel set stone in the ring which is a Bluey Tan in color. I am unsure what the stone is. The ring is a size 8 and the silver is substantial. It is not marked, but I guarantee it to be sterling. The ring is 7/8 of an inch along the finger. I do not think this is an Opal, but when held in the light the Blue is Vibrant.
