Ring Size Guide

At Natasha Schweitzer we use UK/AU ring sizing.

To determine your ring size you can use a ring sizer, available to purchase online here.

Alternatively, you may visit any of our boutiques to have your finger professionally sized, or visit a trusted local jeweller.

If purchasing online, you may also select TBC as your ring size, and our customer care team will contact you to arrange a ring sizer to be sent to you.
