I haven't been wearing earrings much lately but yesterday I wore my diamond studs - 1 ct each earring. One of them went missing. I was really worried looking all over the place. fortunately it turned up inside my top but I haven't found the jumbo back. I'm thinking the cause of this may have been putting on and taking off the mask. don't think I'll wear any expensive earrings again until this awful mask thing is over.
