    Size Guide


    To determine your ring size, you can purchase a ring sizer here

    Alternatively, you can use a string or piece of paper to complete a circle around your finger. Using a pen, mark the string or paper at the circle’s connection point. Then use a ruler to measure the length of the string/paper from the top until the mark, and compare with the table below.

    At Natasha Schweitzer we use UK/AU ring sizing.

    Please note that in some cases the base of your finger may be smaller than your knuckle, so please take this into consideration when sizing.

    In doubt, we strongly recommend a visit to your local jeweller to accurately ascertain your ring size.
