Silver tone w/blue,brown, silver beads-hoop pierced earrings

Earrings are in fair condition and kept in a clean smoke free home. They had a lot of tarnish. I scrubbed around the area that goes into the ear the most. Some of the beads still have tarnish or is it a faded black coloring? Some of the blue have discoloration as well on the sides that are not seen because they are up against each other. No markings but possibly had a silver finish because they had a never ending tarnish. Wire hoop earrings dangle approximate 2 1/4” X 1 2/4 wide. #piercedearrings #beadedhoop #hoop #hoop-earrings
