Small or large ring sizes

Most of our collection of ladies' rings are available in sizes I to S, and our men's rings in sizes P to Z. However if you require an alternative size our team can order this for you. Or, if you require the piece of jewellery more urgently, we may be able to resize the ring you have chosen. Unfortunately not every ring design is suitable for resizing, but our team will be able to advise you as to whether the jewellery you have chosen can be adjusted.
