Please store each piece in a hard box or zip-lock bags to avoid bending and tangling. Use a polishing cloth as needed to prevent tarnish (you can buy them at any jewelry store, or drug store), the more you wear the piece the less it will tarnish. I am also happy to clean and repair my own jewelry for you for free within the first 3 months of purchase, after that there may be a charge. Please feel free to send us an email using our contact form.
