Not sure of your ring size? You're not alone — it's the most common question we get. Our rings come in sizes 3.5 to 9.5, in quarter sizes, so we can almost always land on a fit that feels right.

How to measure at home

Option 1 — measure a ring that already fits. Lay it flat and measure the inside diameter (straight across the center of the opening) in millimeters. Match it to the chart below.

Option 2 — measure your finger. Wrap a thin strip of paper or string around the finger, mark where it overlaps, and measure that length in millimeters. That's the inside circumference in the chart below.

A few tips: measure at the end of the day (fingers run slightly larger), measure a few times and average, and if your knuckle is much wider than the base of your finger, size for the knuckle — the ring has to get over it. Between sizes? Go a quarter size up.

Measurements are approximate and can vary slightly by ring width — wider bands usually fit a touch snugger.

Keep it simple: wipe with a soft, dry cloth after wearing and store pieces separately in a pouch or box. Keep jewelry away from perfume, lotions, and household cleaners, and take it off before swimming, showering, or working out. Reach out any time for a professional cleaning or inspection.
