Size Guide
Every product page lists the sizes available for that particular piece. This guide explains what those sizes mean and how to measure, so you can order once and keep it.
Ring Sizes
Our rings are listed in US sizes. Most designs run from 5US to 13US; a few start at 3US or 4US. Some rings are marked Adjustable, meaning the band is open and can be gently eased to fit.
| US size | Inside diameter | Inside circumference |
|---|---|---|
| 4 | 14.9 mm | 46.8 mm |
| 5 | 15.7 mm | 49.3 mm |
| 6 | 16.5 mm | 51.9 mm |
| 7 | 17.3 mm | 54.4 mm |
| 8 | 18.1 mm | 57.0 mm |
| 9 | 18.9 mm | 59.5 mm |
| 10 | 19.8 mm | 62.1 mm |
| 11 | 20.6 mm | 64.6 mm |
| 12 | 21.4 mm | 67.2 mm |
| 13 | 22.2 mm | 69.7 mm |
How to measure your ring size at home
Wrap a strip of paper or a piece of string around the base of the finger, mark where it overlaps, then measure the length in millimetres against a ruler. That measurement is your inside circumference — match it to the table above. If you land between two sizes, take the larger one.
Two things worth knowing: fingers are slightly larger at the end of the day and in warm weather, so measure then rather than first thing in the morning. And a wide band feels tighter than a thin one at the same size, so consider going up half a size for anything chunky.
Bracelet Sizes
Bracelets are listed by total length. The most common range across our collection is:
| Length | Centimetres | Typically suits |
|---|---|---|
| 5.5 in | 14 cm | Children, or a very slim wrist |
| 6.2 in | 16 cm | Small wrist |
| 7.0 in | 18 cm | Average wrist — the most popular size |
| 7.8 in | 20 cm | Larger wrist, or a looser drape |
| 8.6 in | 22 cm | Large wrist, or a deliberately loose fit |
Some pieces use slightly different steps (19, 20 and 21 cm), and some are Adjustable. The options shown on the product page are always the ones actually available for that piece.
How to measure your wrist
Wrap a tape measure snugly around your wrist just below the wrist bone, then add roughly 1.5–2 cm for a comfortable everyday fit, or 2–3 cm if you prefer a bracelet that moves.
Necklace and Chain Lengths
Chains are listed in centimetres with the inch equivalent. Our most common lengths:
| Length | Inches | Where it sits |
|---|---|---|
| 45 cm | 17.7 in | Just below the collarbone — the most versatile length |
| 50 cm | 19.7 in | Top of the chest, good for showing a pendant |
| 55 cm | 21.7 in | Mid-chest, works well over knitwear |
| 60 cm | 23.6 in | Below the bust, or as a layering piece |
For a layered look, leave at least 5 cm between chains so each one reads clearly.
