Ring Sizes

By Diameter -
To easily find out your ring size, take an existing ring and measure the inside diameter with a ruler from inside edge to inside edge and check it against our Diameter chart below.

OR

By Circumference -
If you don’t have an existing ring, you can measure by wrapping a small strip of paper around your finger, mark where they overlap and then fletten this out mesuring from the end to the mark. You can then check this measurement against the Circumference chart.

Please Note: Finding your ring size by these methods may not be completely accurate. Have your finger professionally measured for a more precise measurement, they can advise on the most suitable size for you.
