Size FAQ
What does gauge describe?
Gauge describes jewelry thickness. Use the gauge shown on the product page and confirm compatibility with your piercing.
Can I choose a size from a photo?
A photo does not provide a reliable measurement. Compare stated dimensions with a known fit or ask a qualified piercer.
What if I am between options?
Fit depends on placement, anatomy, jewelry style, and personal preference. Seek professional sizing guidance rather than guessing.
