How to measure your ring size

Using a ring you already own that fits perfectly, measure the inside diameter of the ring with a ruler in either millimetres or inches.

Write down the measurement and match it to the chart above. If your size falls in-between two sizes we suggest buying the larger size.

If you are still unsure about your ring size and you would like further assistance, please email us at customercare@astridandmiyu.com.

Necklaces

Our chain necklaces, pendant necklaces & chokers range between lengths of 33cm-50cm. Most of them have an extender chain, so you can add up to 5cm to the length of the chain.

We have all the lengths required for the perfect graduated necklace stack!

Bracelets

Most of our bracelets come in a smaller size & larger size, so you can find a bracelet to fit you! Sizes range from 18cm - 21cm.
