Ring Size Chart

If you are ordering a ring, we will need to know the finger size you require. You can select the appropriate size using the chart below or come in to our store and we will gladly measure using our ring size gauges. We use the British ring size standard, but have included the equivalent overseas sizes for the benefit of our overseas customers and tourists.

Tip: Cut a strip of paper no wider than 1.5cm and at least 8cm long. Then wrap it around the base of the finger

It's a good idea to wrap the paper around your knuckle as well as the base of your finger and make modifications, as needed, so the ring size will not be too tight for your knuckle or too loose on the base of your finger.
