Jewellery size guide
Enigma's jewellery size guide will help you find the right signet ring size and the best fit for your bracelet. Use the information below to measure and choose your jewellery size.
All our designs are carefully developed and made by skilled jewellers. This means every piece in our range can be made to order to suit your design, material or size requirements. Please contact us to discuss personalising your jewellery.
01Bracelets
To find your bracelet size, follow these steps:
- Measure your wrist at its narrowest point, just below the wrist bone — ideally with a flexible measuring tape or a strip of paper.
- If you use a strip of paper, mark where it meets around your wrist. Lay it flat and measure it with a ruler. This is your wrist measurement. Add 1–2 cm, depending on whether you prefer a closer or looser fit.

02Signet rings and rings
The most accurate way to find your ring size is to visit a jeweller and have your finger measured with sizing rings. Alternatively, you can order our reusable ring sizer. If neither option is available, follow these steps:
- Wrap a piece of string or a strip of paper around the base of your finger.
- Use a pen to mark the point where the ends meet.
- Measure the string or paper with a ruler marked in millimetres.
