3. How to Measure Your Jewelry
Straight Stud / Barbell
When measuring the length of a post, only measure the straight linear wearable bar in millimeters (mm). Do not include the screw-on balls, flat backs, or decorative charms.
Hoops & Rings
When measuring rings or hoops, do not measure the outside edges. Always measure the widest inner diameter across the internal opening of the hoop.
