When you purchase a ring on Zalesoutlet.com, you will be shown the size (or sizes) in which the ring is available. If you select a size other than the standard ring size shown, service may be required to adjust it. Ring sizing service will take up to three additional business days. Certain metals such as tungsten and titanium cannot be sized. If you do not see your ring size listed for a ring you like, please visit the Zales Outlet store nearest you to determine if a ring can be ordered in your size.
