This is a very nice ring , circa 1900. It is gold, and has several marks on the shank, but I don't recognize them. We have 3 emeralds making a band around a sheaf of ten rose cut diamonds. Then, there are three more rose cut diamonds, flanking either side of the diamond sheaf. The ring is a size 6 and 1/2, but it could be sized. The top measures 3/4 of an inch North to South, and 5/8 of an inch East to West. The diamonds are set in silver, and are closed back. This is a very pretty, feminine ring.
