Go to Hobby Lobby - look in the bracelet/trinket/bangle section and look for tiny, tiny discs.
They are for either bracelets or rings. Made out of copper but plated.
I bought a bag of tiny ones for a dollar or so. Trim the ring tag off, flat it down with 320 paper and put a weeny blob of epoxy on and stick over the offending rivet.
When set, wet and dry over to remove edges and then prime and touch up.
Move on, fly on
