Ring Size information

ring size information and charts

Ring Size information for ladies UK and international.

This helpful guide to ring size is aimed at conversion from UK ring sizing to other countries internationally; as we normally just give just the information on UK size for all our rings sold.

First you do need to measure your finger that you intend to have the ring on. I would recommend  buying a ring sizer as they are available from many jewelers or just use a piece of string, wrap it around your finger not too tight and carefully measure the length. Don't forget that a ring with a thick band will need to be slightly larger in size and that UK sizes go from A (small) to Z (largest).

This is however an estimated guide and fingers do differ in size through out the day, being smaller in the morning to their night time size. For our costume and vintage rings for sale. Also see our resin and acrylic rings available.
