Values marked with ~ sit between standard gauges — order by millimeter when you're between rungs.
How to measure
- Remove the pair you currently wear.
- Lay a rigid ruler across the widest inner diameter of the piece — edge to edge, not the flare or lip.
- If you sit between rungs (e.g. 13mm), size down — most heavier metals wear tighter than silicone or acrylic.
Stretching up
Never jump more than one full millimeter at a time. Wait 6–8 weeks between stretches. Stop immediately if you feel pressure, thinning, or blowout. Slow is permanent; fast is scar tissue.
A note on weight
Solid gold and sterling silver wear noticeably heavier than acrylic or silicone. Rotate with a lighter pair on long days, especially in the first months of a fresh stretch.
