Hi Lotus and welcome,
Very cool design on your earrings! Are they quite old? Thanks for the photo! Recommend a silver polishing cloth, and take your time. (Many jewelry stores sell them for approx $10.) A bit of oxidization may remain where the wire is wrapped, but I think it will enhance the vintage look. Please don't dip the whole earring in any liquid tarnish remover; that would likely damage the pearls, which have very nice luster. Others may have suggestions, too.
