Unfortunately, we do not offer ring resizing services at Isaac Wolf. We highly recommend that you get your finger sized properly before making a purchase to ensure that the ring fits perfectly. We offer a wide range of ring sizes for our customers to choose from, so you can find the perfect fit without having to worry about resizing. If we do not offer the size you're looking for you can contact us and make a request for that size and we'll do our best to provide it as soon as possible. If you have any further questions or concerns, please don't hesitate to contact our customer service team. We are always happy to assist you in any way we can.
