Ring Sizing


To determine your ring size, use a piece of string and wrap it around the base of your finger. Use a pen to mark the point on the string where the end meets. Use a ruler to measure the string. Choose the closest measurement to the chart below to find your ring size. 

Orion's Belt Jewellery strongly recommends a visit to a local jeweller to accurately determine your ring size.
