C de Cartier wedding ring, 5 mm width, 1 diamond

For the most accurate measurement, please measure your wrist directly, instead of measuring another bracelet.

MEASURING GUIDE

1. Using a length of string or ribbon, wrap it around the base of your wrist. To ensure a comfortable bracelet fit, we recommend measuring the thickest part of the wrist, usually the wrist joint. 
2. Mark the point on the string with a pen where the end meets.
3. Measure the string in millimeters (recommended) or inches with a ruler.

Alternatively, you may use our printable sizer to measure your wrist. Download the printable sizing tool

MEASURING TIPS

• Remember that the left and right wrists differ slightly in size.
• For a looser fit, select one size up from the size recommended in this guide.

IF YOU HAVE A RING

You may refer to the size of your existing ring if you plan to wear it on the same finger. Check if your ring has its size engraved on the inner surface and verify its size by downloading the printable sizing tool. 



We recommend using a basic ring design such as a wedding band; otherwise, you may try with various ring shapes. Please note that wider rings may require a larger size than those with smaller widths.

IF YOU dont HAVE A RING

For the most accurate results, we invite you to Book an Appointment at your nearest boutique for assistance in finding your size. 

CHOOSING THE RIGHT SIZE

Your ring is the right size if:

• You can easily put it on
• It can rotate around the finger
• You do not lose it when you move

Finger size may vary slightly throughout the day, you may need to try it multiple times to confirm a comfortable fit. Please note that the same fingers on different hands will likely differ in size.

If you remain unsure, our complimentary return policy will allow you to exchange your ring for a different size. Please note that engraved rings or rings showing signs of wear will not be eligible for return.
