This pair of sterling napkin rings are in excellent condition with minimal wear. They are not monogrammed. The border is plain and the middle curves inward. Stamped with the Birmingham hallmarks and the 1925-6 year mark. The silversmiths are R&S in rectangle and I cannot find that exact match so for now the silversmiths name is unknown. The rings are 1 7/8" in diameter and 1 1/4" tall. Although plain, this is quite a nice set. Sterling weight is 29.3 grams for both.
