Vintage blue rivoli and chaton rhinestone pin and clip earrings set. The metal has a black Japanned finish. The pin measures 1 3/4" in diameter. The earrings measure 1" in diameter each. The rivoli rhinestones are Montana blue. This set is not signed. The earrings have the typical Shreiner clip back finding but I cannot find another so I cannot attribute this set to any company. Condition is good.
