Rings
Many of our rings are adjustable and fit most fingers, so you only need a size for our fixed-size styles.
| UK size | US size | Inner diameter | Inner circumference |
|---|---|---|---|
| J½ | 5 | 15.7 mm | 49.3 mm |
| L½ | 6 | 16.5 mm | 51.9 mm |
| N½ | 7 | 17.3 mm | 54.4 mm |
| P½ | 8 | 18.1 mm | 57.0 mm |
| R½ | 9 | 18.9 mm | 59.5 mm |
| T½ | 10 | 19.8 mm | 62.1 mm |
How to measure your ring size at home
Method 1: Use a ring you already own. Place a ring that fits on a ruler and measure the inside diameter in millimetres. Find the closest diameter in the chart.
Method 2: Measure your finger. Wrap a thin strip of paper or string around the base of your finger, mark where the ends meet, then lay it flat and measure it in millimetres. Find the closest circumference in the chart.
Tips for the perfect fit
- Measure at the end of the day, when your fingers are at their largest.
- Avoid measuring when your hands are cold.
- If you're between two sizes, choose the larger one.
- Wide band rings fit more snugly, so consider going half a size up.
Necklaces
Necklace length is measured end to end, including the clasp. Here's roughly where each length sits:
| Length | Where it sits | Best for |
|---|---|---|
| 35–38 cm | Close to the base of the neck | Choker look |
| 40–42 cm | On the collarbone | Dainty pendants, everyday wear |
| 45 cm | Just below the collarbone | The most popular length, great for layering |
| 50 cm | Above the bust | Pendants with higher necklines |
| 60 cm+ | At or below the bust | Long, statement layering |
The exact length of each necklace is listed on its product page. Many of our chains have a small extender so you can adjust the fit. Our personalised name necklaces come in 40cm, 45cm or 50cm.
Layering tip: leave about 5cm between each necklace so they sit nicely and don't tangle. See our stacking guide for more ideas.
Bracelets & bangles
How to measure your wrist
- Wrap a strip of paper or a soft tape measure around your wrist, just above the wrist bone.
- Mark where the ends meet and measure the length in centimetres.
- Add 1–2 cm for a comfortable fit.
| Wrist size | Fit |
|---|---|
| 14–15 cm | Small |
| 15–16.5 cm | Medium (most common) |
| 16.5–18 cm | Large |
Most of our chain bracelets are around 16cm with an extender chain, so they adjust to fit most wrists. Our open bangles and cuffs are approximately 6cm across and slip on from the side. The exact size of each piece is listed on its product page.

Hand chains
Our hand chains have a bracelet of around 16cm, usually with an extender, and a ring loop for the middle finger. The bracelet adjusts to fit most wrists, and the chain sits loosely across the back of your hand.
