Kora Green Tourmaline Ring with Diamond Pavé

Measuring your ring size from home

Using an existing ring 

You can measure the internal diameter of an existing ring for the desired finger and use the below size guide to determine your size. 

Alternatively, you can download and print our ring size guide at 100% size. Place your ring on the different circles until one matches up exactly with the inside of your ring.

String Method 

Wrap a string or a thin strip of paper around your finger and mark the spot where the string or paper meets. Measure the distance with a ruler in mm. Use our ring sizing chart below to determine your desired ring size. 

Alternatively, our guide has a sizer which you can use to measure your ring size.

Useful Tips

• Wider bands typically feel tighter than a thinner one - we suggest one full size larger for a comfortable fit.
• If your ring size falls in between 2 sizes, choose the larger of the sizes. 
• Your fingers tend to be at least half a size smaller when its cold and swell when its hot. We recommend having warm hands when measuring. 
• Your fingers expand and contract throughout the day. We suggest measuring your size at the end of the day when your fingers are at their largest to ensure a comfortable fit. 
• Usually, your dominant hand is slightly larger than the non-dominant hand. 
• Salt and alcohol can make your fingers swell, so avoid measuring your ring size right after a night out or a meal.
