page-embed | Ring Sizing Chart A

If you do not know your ring size, we suggest visiting a nearby jeweller to have them assess your ring size in person. When measuring, opt for a ring with a similar width or as closely matched to the one you intend to buy.

When measuring at home, wrap string around the designated finger at a tightness that feels good to you. Mark the meeting point of the two ends and take the measurement of the length against a ruler to determine the circumference. Otherwise, you can measure the inner diameter of an existing ring as a guide.
