2 pairs of vintage silvertone round earrings with enamel

2 pairs of vintage round silvertone stud earrings with enamel. Blue, yellow, teal. 1980s or 1990s. •Silvertone ~1" round stud earring with enamel in tones of glittery teal and yellow. •Silvertone ~¾" round stud earrings with enamel in glittery navy blue. These earrings are vintage in used condition! I do my best to show any flaws. Some wear due to age is to be expected. I have cleaned the back and post of the earring with isopropyl alcohol. I encourage you to sterilize before wearing as well. Some earrings have metal backs that stuck with them, and the rest have new soft plastic backs. If you have questions or need a measurement, feel free to ask!
