RING SIZE CONVERSION CHART

To ensure you select the right size, we recommend using our sizing chart as a guide. This chart is for reference only, and Nérée Jewellery cannot be held responsible for any inaccuracies.
 

MEASURE YOUR FINGER
Wrap a flexible tape or string around the finger where the ring will sit. Mark where the ends meet and measure the length in millimeters. Compare your measurement to the sizing chart. If you fall between sizes, choose the larger one for a comfortable fit.

 

MEASURE AN EXISTING RING
Use a ring that fits the intended finger. Measure the inner diameter in millimeters. This corresponds to your ring size (e.g., 15 mm = size 47). If your measurement falls between sizes, select the next larger size.


Note: At-home measurements may have slight variations.
