We suggest you visit us and try on our standard sizing rings. If you are ordering from our website we can send you a plastic multi sizer to measure your own finger and send the sizer back to us. When you are trying on rings for size, bear in mind whether your hands are in a thicker, thinner or normal state for you at the time. (e.g. cold hands are usually a bit smaller than hot hands). In most cases it is easier to size a ring up a little bit after it is made. Some rings cannot be sized down later without risk of damage to set stones or other components of the ring. If in doubt please discuss your concerns with us before ordering a specific size.
