Ring Size Guide
Find your perfect fit with our comprehensive sizing guide
-
Wrap a piece of string or paper around the base of your finger. Mark where the ends meet, then measure the length in millimeters. Compare this measurement to our size chart to find your perfect fit.
-
If you're between sizes, we recommend choosing the larger size for comfort. Rings should slide over your knuckle with slight resistance and fit snugly at the base of your finger.
-
Yes, wider bands typically require a slightly larger size than narrow bands. We recommend going up half a size for bands wider than 6mm for optimal comfort.
-
Most of our rings can be resized within 1-2 sizes. However, eternity bands and rings with intricate designs may have limitations. Contact our customer service for specific guidance on your piece.
-
We offer complimentary resizing within 30 days of purchase. Simply contact our customer service team, and we'll arrange for your ring to be adjusted to the perfect fit.
