How To Measure

Measuring Guide: Ring

01

Wrap a string around the base of your finger

Make sure the string is pulled snug (the tighter the better) to find your best fit.

02

Mark where the string meets

With a pen or your other hand, mark where the string meets. Make sure it is pulled snug.

03

Measure the string with a ruler

Lay your string against a ruler and measure the length (cm). This number is your finger circumference. Compare it to our size chart to find which size is right for you.

A good rule of thumb is to measure your finger AND your knuckle to make sure you can slide your ring on & off easily.

Bracelets

How To Measure

Measuring Guide: Bracelet

01

Wrap a measuring tape around your wrist

Measure just below the wrist bone, where you would normally wear a bracelet.

02

Mark where the measuring tape meets

Pull the measuring tape snug (but not too snug), and mark where the measuring tape meets.

03

Compare your wrist circumference to the size chart

Do not add extra length to accommodate for fit; our size chart is based off your wrist circumference.
