Size & Fit Guide
Find the right fit, every time.
Finding the right size ensures your jewelry fits perfectly and feels comfortable every day. Use the guides below before placing your order — we are unable to accept returns for sizing or fit issues.
Ring Sizing
Method 1 — String or paper strip: Wrap a thin strip around the base of your finger, mark where it meets, and measure the length in millimeters. Method 2 — Measure an existing ring: Place a well-fitting ring on a ruler and measure the inside diameter.
