Ring Size
Don’t know which ring size to go for? We have some simple steps here to help you find your perfect ring size.
If you have a ring that fits your finger, simply measure the internal diameter of the ring and find out your ring size from the chart below.
If not, use a piece of string or a strip of paper and wrap it around the base of your desired ring finger.
Use a pen to mark the point on the string where the ends meet.
Use a millimeter ruler to measure the string.
Choose the closest measurement to the chart below to find your ring size.

If you're between sizes, we suggest to choose the bigger size. If your knuckle is particularly big, you may want to choose a bigger ring size so that the ring can fit over the knuckle.
