Our rings are made to size. If your Alexa Martha Designs ring doesn't fit well, we will need to make a new ring from the model you ordered. I use mostly wire to  create the rings. Wire wrapped rings can't be resized as well for this reason. However. if you must return the ring  return within 30 days of its original shipment date). Make sure you ship the order back insured and signature required.   Call us at 406-241-4502 or email alexa@alexamarthadesigns.com to get the details and our shipping address.
