The sizing of rings is often a tricky process. Many factors including air travel, spicy foods, alcohol and hot weather can dramatically influence finger size. Mon Coeur guarantees that rings will be the size ordered; however, we cannot guarantee the size of your finger.

If you believe that your hand may be swollen, we strongly suggest a ring ordered not be processed until an accurate size is determined, by a reputable jeweler in your home city or by using a ring gauge which we can provide.

Ring Re-Sizing services are available please ask us for a price quote.
