Size Guide

The right measurements for rings, necklaces and bracelets that fit well from day one.

Rings

How to measure your size

  • With a ring you already own: measure the inner diameter in millimeters with a ruler and check it against the table below.
  • With a string: wrap it around your finger, mark where it overlaps, measure the length in millimeters and divide by 3.14 to get the diameter.

If you're between two sizes, always choose the larger one — especially if your knuckles are wider than the base of your finger.

Necklaces

The most common lengths and where they fall.

  • 40 cmChoker, close to the base of the neck
  • 45 cmBelow the collarbone — the most versatile length
  • 50 cmAt chest height
  • 60 cmLong, over the chest — ideal for layering

Bracelets

Wrap a tailor's tape (or a string, then measure it with a ruler) around your wrist, just below the bone. Add 1–1.5 cm for a comfortable fit, or keep the exact measurement for a snugger one.
