Please visit a physical jewelry store to measure the inner diameter of the ring that fits your finger, and then choose the size according to our size chart. This way, you will get the most suitable ring. If you are unable to test it in a store, you can measure it using the method described below.
Step 1:
Take a string or a strip of paper and wrap it around your finger.
Step 2:
Make sure the string or paper strip is snug but not too loose or too tight around your finger, so you get the correct size.
Step 3:
Mark the spot where the string or paper strip overlaps.
Step 4:
Measure the length of the string or paper strip in millimeters. Compare the circumference with the chart below to find your ring size.
Step 5:
If your measurement falls between two sizes, please choose the smaller size. If you already have a suitable ring, you can simply measure the inner diameter of the ring to select the correct size.
