To ensure you are choosing the right ring size for you, measure the circumference of your finger in mm using a tape measure at a time when you are neither hot nor cold. Ensure that the chosen size passes easily along the full length of the finger. Remember that the two hands differ slightly in size; a ring worn on a finger of the left hand will not be a perfect fit for the same finger on the right hand.
