Unusual design vintage .925 silver ring with individual side by side settings, one with an opal and the other onyx. Marked .925, but I cannot make out the maker due to the style of the ring. It's in good condition, but may be missing teeny stones or embellishments, which is not highly noticeable in person as opposed to the magnified photos. Also, the opal feels a bit rough in one spot, so may be a chip. The ring is about a size 8.
