Ring Sizes - How do I find out my Ring size?

I use the circumference of the inside of the ring in mm for my sizing. This way you can get a piece of string wrap it around your finger and measure the length, allowing room to get over the knuckle. So size 55 is a 55mm long piece of string. Below is a chart for converting to US and British sizes. If you are unsure of your size I recommend seeing a jeweler to get your exact size.

The chart below is as accurate as possible please be aware that I am not responsible if you choose the wrong size. Although I am happy to swap it for the correct size if you send it back along with a self addressed pre paid postal bag.

Re-sizing is available if I do not have your size. This is possible for a fee of $20.
