How to measure. Wrap a thin strip of paper around the base of your finger and mark where it meets. Measure the length in mm — that's your circumference. Measure at the end of the day when fingers are at their fullest, and always measure the hand you'll wear the ring on. If between sizes, size up.

Layering. Vary lengths by at least 2" to avoid tangling. A 16" piece paired with an 18" or 20" creates a clean, intentional stack. Each Jude piece listing notes the exact chain length.
