This is a lovely little natural pearl and ruby ring. It is closed backed with foiled stones, and all looks original to me. It is gold, 9 ct. ,unmarked but tested, and a size 3 and 1/2 to 4, but could easily be sized. The ring is circa 1820, and in excellent condition. The decorated top measures 7/8 of an inch East to West, and 1/2 inch North to South.
