Rhodium plated key prong set keystone shaped faux-sapphires with round and baguette clear accents brooch with security clasp. Marked only with an inventory number which looks to be "6012" which would date to the 1950s. Measures: 1 inch long by 13/16 inches. Condition: Very good; top clear baguette has some faint aging, perhaps a bit of aging to the tiny clear rhinestones, but nothing real noticeable.
