Most of our rings can be sized up or down by two sizes. If a ring has stones set all the way around the band it cannot be sized but most times we can custom order it in the size you need. Please allow additional processing time for sizing and an additional fee. Sizing cost varies depending on the metal and if it is being sized down or up. Please add a note at check-out with the size you need. Text 708-386-8400 with any questions or to get a sizing quote.
