RING SIZE
Measure your ring size when your hands are warm and you have been active for at least a few hours. Activity and temperature can change the size of your fingers which are at their largest when they are warm, especially towards the end of the day. Contact us to request a ring size chart to find the ring size that fits comfortably and snugly at the very base of your finger. This is your normal ring size.
