Ring sizes
Wrap a thin strip of paper around the base of your finger, mark where the ends overlap, and measure the length in millimetres — that is your circumference. Match it to the row below in whichever standard you know your size in.

Ordering from somewhere not listed above (UAE, Singapore, Malaysia, Mexico, Indonesia, Vietnam, Saudi Arabia)? Use the Circumference or Diameter (mm) columns — that measurement is exact no matter what your local sizing system is called. Tip: measure in the evening, when fingers are slightly larger due to warmth. Not sure between two sizes? Pick the larger — we offer one free resize within 60 days.
Bangles sizes
Measure the circumference of your wrist with a tape measure or string. Choose a bangle length 2–3 cm longer than your wrist for a comfortable fit. This is a physical measurement, not a regional standard — the same length fits the same wrist anywhere in the world.
| Wrist Size (cm) | Recommended Bangle Length |
|---|---|
| 12–13 cm | 15 cm |
| 13–14 cm | 16 cm |
| 14–15 cm | 17 cm |
| 15–16 cm | 18 cm (standard) |
| 16–17 cm | 19 cm |
| 17–18 cm | 20 cm |
| 18–19 cm | 21 cm |
| 19–20 cm | 22 cm |
Necklace lengths
Necklace lengths are measured end-to-end. The guide below shows where each length sits on an average build — this may vary slightly depending on your frame. This is a physical measurement, not a regional standard — the same length sits the same way anywhere in the world.
| Length (inches) | Length (cm) | Sits at |
|---|---|---|
| 14″ | 35 cm | Choker — high on neck |
| 16″ | 40 cm | Collarbone |
| 18″ | 45 cm | Just below collarbone (most popular) |
| 20″ | 50 cm | Chest |
| 22″ | 55 cm | Upper chest / sternum |
| 24″ | 61 cm | Below sternum |
| 28″ | 71 cm | Waist |
| 30″ | 76 cm | Below waist (opera length) |
