What’s your ring size?

Finger sizes vary from one person to the next and it can be almost impossible to get right just by guessing. So it’s important to check your ring size before ordering a ring from our jewelry store - or from anywhere else for that matter.

But how do you make sure you have the right size? We know it can be tricky, so we're here to help.

Because you'll want an accurate measurement we highly recommend purchasing one of our very handy ring sizing kits.

Each kit contains a reusable sizing belt, a printed copy of our very helpful measuring guide and even a discount code to use when you return to shop online for rings. 

If you already know your ring measurement or need to convert a ring size, scroll down to our ring size conversion chart, which includes both US and Australian ring sizes.
