This is a lovely vintage Art Deco ring in sterling silver set with an oval faceted topaz glass stone flanked by 3 small clear glass stones on either side. It is marked Orlando Sterling on the inside of the shank. I have not been able to identify this maker, however I have been able to find a couple of references to this mark which indicate that it is from this era.
The ring is a size 6 3/4 and it is in very good condition. The small clear stones have darkened somewhat but since they are tiny it is not that noticeable.
