Ring Size Guide

Your fingers will be at least half a size smaller, when your hands are cold and larger when you hands are hot.
Rings with a wide band or stacking design will feel tighter than a thin band and I would recommend choosing a size larger than your normal ring size.
Your ring should be loose enough to slide over your knuckle, but not so loose it will fall off.
