Ring Size Guide

Finding Your Perfect Fit

A ring should feel like a gentle embrace – secure yet comfortable, easy to slide over the knuckle but never loose. We want your Luminesse piece to fit flawlessly from the moment it arrives.

Method 1: Measure a Ring You Already Own

Find a ring that fits the intended finger well. Measure the internal diameter of the ring in millimeters, from edge to edge. Use the conversion chart below to find your corresponding size. Alternatively, place the ring on a printed ring size chart and match the inner circle.

Method 2: Measure Your Finger

Wrap a strip of paper or a flexible measuring tape snugly around the base of your finger. Mark where the ends meet, then measure the length in millimeters. This is your finger’s circumference. Refer to our size chart to convert circumference to ring size.

Tips for Accuracy:

Measure at the end of the day when fingers are at their largest.

Avoid measuring when hands are cold, as fingers contract.

If your knuckle is significantly larger than the base of your finger, choose a size that slides over the knuckle comfortably. We can add sizing beads to keep the ring upright.

Complimentary Sizing Support

We offer a complimentary ring sizing kit – simply request one during your consultation, and we will mail you a set of reusable metal sizing rings. If your Luminesse piece arrives and the fit isn’t perfect, we provide one complimentary resizing within the first year.
