Solid gold does not tarnish but it does need cleaning from time to time. You will know because the gold will look dull. You may use a soft bristle toothbrush and non-chemical soap to clean it or a soft jewelry cloth. Fine jewelry is delicate and should be treated as such. Stones and shells may break if not properly taken care of.
