A very nice lot of vintage shirt studs in assorted styles. There is a pair with clear glass bullet dome shaped cabochons, a pair in 2-tone metal (gold filled or plated) with beautiful iridescent abalone centers, and three with cobalt blue glass centers with a copper finish. The clear glass cabs are about 6mm wide; the abalone ones are 12mm wide including the embossed borders and the blue glass stones are about 5mm wide. The trio with the blue glass centers have some age discoloration on the metal, but the other 2 pair are in excellent shape, and very elegant.
