Measure your finger to get the perfect ring

We provide the ring size chart below to assist you in selecting the correct ring size when making a purchase. Please follow the instructions closely to ensure accuracy.

How to select the correct ring size

  1. Select a suitable ring that fits your finger well without being too tight or loose.
  2. If the ring is misshapes or if you do not have a suitable ring, then it may be best to borrow one from someone else who has a ring that fits correctly.
  3. Measure the internal diameter of the ring, ensuring you measure at the widest point.
  4. Use the ring size chart below to convert to the appropriate international standard ring sizes

Alternatively you can visit any one of our boutiques, where we would be happy to help confirm your correct ring size.
