Yes! If you do not see your ring size when purchasing an item, simply place your order for the closest size and then contact our customer service department at (877) 202-5467 or via email at service@charlesandcolvard.com with the order number. If you need a previously purchased ring resized, you may submit a request through the service portal or contact our customer service team. There are a few exceptions for resize requests. Eternity bands must be ordered to size and some men's styles are not able to be resized.
