Earrings (EUC) colorful glass - jewelry

Earrings are in excellent condition, clean, kept in a clean smoke free home, cat friendly Glass earrings were sold as sterling silver but are not marked. My kit to test sterling is getting old so I tested something I know is sterling and both came out the same so I believe the earrings are sterling - test shown in photos. Sterling usually is blue specks and this is a cloudy blue. Glass earrings are orange/red, and blue/green stripe, and clear. Bottom larger glass bead is 13mm X 5mm , total dangle 1 7/8” No markings, brand unknown. #earrings #jewelry #glass-earrings #pierced-earrings
