THe Mark's Diamonds Guarantee

60-Day Free Resizing

All of your Mark’s Diamonds engagement rings, wedding bands and fashion rings qualify for a free re-sizing once within the first 60 days of its original purchase. To take advantage of your free re-sizing, contact the Customer Service team at 877-766-2757 for instructions on sending us your ring.

Please note that certain rings such as eternity bands or tension rings do not qualify for re-sizing because they must be constructed to size without alteration. Please keep this in mind when purchasing these rings from our website to ensure rings are ordered with the proper size during the initial purchase.
