This is a very pretty and very old Natural Opal ring This ring is size 6 1/4. The opal has a small scratch that you can't see and the ring is not marked. This has a Tiffany six prong setting and sets the little opal very well and it has a lot of pretty color. There is still a lot of love in this pretty ring. It will come in a velvet bag or new ring box. For you from the High Plains of Kansas!
