Ring Sizing Information

How to find out your ring size

If you have an existing ring

Measure the internal diameter of your ring. This is the width of the inner part of the ring that touches your finger. Compare your measurement with the 'diameter' sizes in our chart below. 

If you don't have an existing ring

Use a piece of string and wrap it around the base of your finger so it fits but is not too tight. Use a pen to mark where the end of the string meets to complete a circle. Measure from the end of the string to the pen mark. Compare your measurement with the 'circumference' sizes in our chart below.

If you need further assistance, please call us and we will help you choose the right ring size for you.
