Ring Sizing

How to Find Your Perfect Ring Size

1. Determine which finger you want your ring to fit on.

2. Grab a string or piece of paper and wrap the string around it, making a mark where the ends meet.

3. Take the string and lay it flat against a ruler, noting where the mark hits in mm.

4. Use our sizing chart to find which ring size will fit you best!
