How to Determine Your Size

Discover Your Perfect Ring Fit

Method 1: Using an Existing Ring

Select a ring that fits the specific finger you intend to wear it on.
Measure the inner diameter of the ring in millimeters using a ruler or tape measure.
Compare your measurement with our sizing chart to find the corresponding size.

Method 2: Measuring Your Finger

Cut a small piece of string or paper, about 10 cm in length.
Wrap the string around the base of your finger where the ring will rest, ensuring a snug but not overly tight fit.
Use a pen to mark the spot where the ends of the string overlap.
Straighten the string and measure the length between the two marks in millimeters.
Use this measurement to determine your size from the chart provided.

Professional Advice

The ring finger on your dominant hand may be a different size than on your non-dominant hand, so be sure to measure the correct one.
If you don't have a string, a thin strip of paper can serve the same purpose.
For best accuracy, we recommend measuring at least twice.
The most accurate results are often obtained by measuring in the afternoon when your hands are warm.
If the ring you are buying is particularly wide, you may want to consider a slightly larger size for a comfortable fit.
Don't hesitate to reach out to our Customer Service team if you are uncertain about your size.
