The H.Samuel specialist ring size service

The easiest and most accurate way to find your ring size is to have your finger measured by one of our friendly, trained and professional staff at your local H.Samuel store. Using an industry-standard ring sizer, which is a selection of metal rings in all the different ring sizes, they will quickly ascertain your ring size for you. If you are purchasing for a friend or a loved one, try to borrow one of their rings, preferably one with a similar width and style, and take it along with you to be measured.

Extra large or extra small

Most of our rings for ladies are available in sizes I to S and most of our men's rings are available in sizes P to Z. If you require a ring size outside of this range, visit your local H.Samuel store and we will order one especially for you. Your ring may take several weeks to arrive. If you want your ring more urgently, it may be possible to have the ring you have chosen resized for you. Please note, however, that some rings cannot be resized because of their style. A member of staff will advise you a particular ring can be resized
