As a courtesy, we always confirm finger sizes when customers want their rings engraved before trying them on. If you like, we could send you the ring without the engraving first, then you could make sure it fits correctly and then send it back to us to have it engraved. This way if the size is wrong you will not have to pay another $35 to get the correct size engraved. If not, simply choose "Ship Ring With Engraving" to let us know you want to go ahead and have the ring engraved and we will continue processing your order with no changes. By the way, engraving will add 1 extra day to order processing time. Thank you.

Ring Width Guide

If you don’t happen to have a ruler nearby, an everyday object we have found that gives an accurate representation of the width of a ring is a 5¢ US nickel.  The thickness of a nickel is basically 2 mm thick.
