Size guide

Get the size right before we make it. Every approval comes with a free ring sizer, so you can double-check before we start.

Rings

Three ways to find your size

  1. The free sizer. The most accurate: we post one with every approved preview, before we make your ring.
  2. A ring you already wear. Print the sizer below and lay the ring over the circles. Your size is the circle that fits just inside the ring.
  3. A strip of paper. Wrap it round the base of your finger, mark where it meets, measure the length in millimetres and find it in the circumference column.

Good to know

  • Measure at the end of the day, when your fingers are warm.
  • Between two sizes? Choose the larger one.
  • Wide bands, like the wide pavé and men's bands, sit snugger: go up a half size.
  • Eternity and full pavé bands can't be resized later, so be sure of these.

Bracelets

Tennis bracelets and chains

Measure your wrist snugly with a tape or a strip of paper, then add about half an inch (13 mm). Most people wear 7 inches.

Bangles and cuffs

A bangle has to slide over your hand, so measure your wrist and add about an inch. Ours come in small (6.5 in inside), medium (7 in) and large (7.5 in), and open on a hinge.

6.5 in
Small, a close fit
7 in
The most common
7.5 in
Relaxed, a little movement

Necklaces

Chain length decides where a pendant sits. Hold a string round your neck at each length to see.

16 in
At the collarbone
18 in
Just below the collarbone, the most worn
20 in
Longer, above the neckline
16 in 18 in 20 in
