Yellow Sapphire Diamond Eternity Ring

1. You'll need a piece of paper or string about the same length as your ring finger.
2. Wrap the paper or string around your finger and make sure it fits comfortably. Mark the string or paper at the point it meets.
3. Carefully measure the string or paper in mm on a flat surface with a ruler – from the end to the mark – and enter your finger circumference in our size chart tool to find your ring size.

Another way to measure your ring size is to use a ring that you already know fits the correct finger.

1. Print off our true-to-size guide – double-check that you print to scale using the paper size outlined for accuracy.
2. Put your ring over the circles on the template to find your ring size.
