IF YOUR MEASUREMENT IS BETWEEN THE TWO SIZES IN OUR TABLE, WE ADVISE YOU
TO CHOOSE THE SIZE TO THE LARGER SIDE.
IF YOU DON'T KNOW YOUR SIZE, YOU CAN FIND OUT YOUR SIZE IN TWO WAYS:
1. If you have a ring that fits your finger, simply use its diameter to find the size you need.
HOW TO FIND OUT THE DIAMETER:
- Use a ruler to measure the inside diameter. Place the ruler in the centre of the ring.
- Check our size chart, select the correct range and find the ring size.
2. Recognise the circumference
- Use a piece of string or paper.
- Wrap it around the widest part of your finger, making sure that the thread or paper fits around your finger but does not pinch it.
- Mark the point where the two ends meet.
- Measure the string, paper or paper to get the circumference of your finger.
- Choose the size you need from our chart
