Our ring sizes are based on the inner diameter. If you are unsure about your ring size, measure the inner diameter of a ring you have at home with a ruler. For example, a diameter of 17mm is a size 17, and so on.
It is best to measure using a ring with the same width/thickness you are planning to buy. The thinner the ring, the smaller the size may be in comparison to a wider ring. Also keep in mind that your fingers should not be too cold or too warm when measuring, as this may affect your size. Remember to measure the finger intended for the ring, as our rings are beautiful on different fingers.
Alternatively, use a measuring tape and measure the circumference of you finger to determine the inner diameter.
You can also visit you local jewellers and ask them to measure your finger.
The most common ring sizes for women are 16.5mm (S), 17.5mm (M) and 18mm (L).
