Ring settings can no longer be custom sized as the manufacturer from whom we purchase our rings is no longer sizing the rings. You should know that the manufacturer has a tolerance of 1/4" size either way with the ring settings. In other words, a size 7 may actually measure 6 3/4" or 7 1/4". If this variation is not acceptable to you, please send a comment with your order requesting cancellation of the ring if an exact size is not available.
