Sterling Silver c1920-1930 Art Deco Marcasite Pearl Rose Ring

Art Deco 1920-1930 Stamped sterling inside shank. Dramatic rose set with imitation pearl and marcasite. I don't see any missing marcasite. I left the patina but you could polish it brighter. 1 " length x 1/2" wide. Sz 5.5 but message for sizing service. Very good condition.
