18ct White Gold 1.05ct square emerald cut White Diamond ring

The most accurate way to determine your ring size is to visit one of our Calleija boutiques. One of our expert associates can help measure your ring size. However, we know this is not always possible and below are some instructions on how to do this at home. All you need is a string, thread or ribbon and a ruler.

First, wrap the string around your finger close to your knuckle. Mark the spot where the string overlaps. Hold the string beside a ruler and measure the marked length in millimetres. This is the circumference of your ring. Enter the ring measurement into our Ring Sizer to determine your best Calleija ring size.

You can also match the inside of one of your best fitting rings with a corresponding sized circle on our Calleija Ring Size scale.
