This vintage sun flower or sunflower pin is alight with tiny faceted marcasites. The setting is pierced and finished in bright rhodium plating to resist any tarnishing.
Diameter is 1 3/8" and the center is slightly domed. All the stones are intact and sparkling.
The back has that highly reflective rhodium finish; the pin has a safety clasp. There are no maker's marks but I tested the pin and it is sterling silver; rhodium is used to protect sterling from tarnish. Condition is excellent.
