45 Day Return Policy

At Diamond Design Co. we base our success on your satisfaction, therefore we stand behind our product quality and your satisfaction with a 45-day return policy for all our products (loose diamonds and custom orders may be excepted). If you are not completely satisfied with any item purchased from The Diamond Design Co., we will refund your purchase price (less custom design fees and shipping charges which are non-refundable. If you did not pay for shipping, a flat $20 shipping fee will be deducted from your credit).

We accept returns for refunds on all jewelry items, or gifts, with the exception of items that have been resized, altered, damaged in any way, or the applicable JEWELRY IDENTIFICATION TAG has been removed. If you decide to return your purchase for a refund within 45 days after receipt of your purchase, you must obtain a Return Authorization Code (RAC). which you will need to write on the return shipping label and the original invoice. Packages that do not have a RAC must be returned to sender.

The original invoice must be included in the returned package. Return merchandise, unaltered with ALL original packaging, including the appraisal, gift boxes (undamaged), and signature services card as applicable. We cannot accept merchandise that has been altered or damaged, or is not returned to us within 45 days of original ship date.

Once we have received your package and upon approval, please allow 7-10 business days to confirm credit with your credit card processor.

To request a Return Authorization Code, please go to RETURN AUTHORIZATION REQUEST and follow the instructions.

Ring Re-Size Policy

To avoid unnecessary resizing and shipping fees, prior to placing your order, it is essential to know your correct ring size. While we are happy to assist you with this process, we always recommend going to your local jeweler and trying on similar rings to find the most comfortable size. Alternatively, if the ring is a gift, find a ring of the recipient's and have a jeweler estimate the size for you.

If for some reason, upon receipt of your ring you still require resizing, we will be happy to accommodate you for resizing within 30 days of your purchase plus a small handling fee. Engraved rings require an additional fee to re-engrave the ring. To send back your ring, please go to our Resize Item Page for detailed instructions for sending your ring back to us.

After 30 days, ring resizes are $50, please email us at to get a return authoriziation (RAC) code to return your ring for resizing. Packages sent without an RAC code will be refused.

Important Note About Exceptions:

"Eternity rings" and some custom orders cannot be resized and must be completely remade for a "minimum" cost starting at $150.00, so please know your exact ring size. Contact us for any questions you might have prior to placing your order,
