Size Guide
Rings
To find your ring size wrap a piece of string or floss around the base of your finger and mark where the string overlaps with a pen. Be sure not to pull the string to tight when measuring your finger, if it stretches you may not get an accurate reading. Line it up to a ruler to measure the length in millimeters.
Common ring sizes for women are 6 (16.5 mm) and 7 (17.3 mm).
