Ring Size Guide
A ring should feel secure but slip comfortably over your knuckle. The easiest way to find your size is with a ring you already love wearing.
Option 1 — Measure a ring
- Choose a ring that fits the finger you plan to wear your new Larimar ring on.
- Place the ring on a ruler and measure straight across the inside edges in millimeters.
- Find that inside diameter in the chart below.
Option 2 — Measure your finger
- Wrap a thin paper strip around the finger where you will wear the ring. It should be snug, not tight.
- Mark where the paper overlaps. Check that the marked loop can pass over your knuckle.
- Lay it flat and measure from the edge to your mark in millimeters.
- Find the closest circumference in the chart below.

For best results, measure late in the day and repeat the measurement. Wider ring bands can feel tighter. Available sizes vary by design: please select from the sizes shown on the product page. If you are between sizes, ask us about that specific design before ordering.
