I coat all my work with a special hypo-allergenic jewelry lacquer to prevent tarnishing. Everyone's skin is different, so if your jewelry does tarnish, you can always mail the piece back to me and I will re-clean and re-lacquer the piece for $5.00. If you email me through the site and do not hear back from me within 2 weeks, it means I did not get your message, so please call me. I'm always happy to take your phone calls and give you more details about my work.
