Ring sizes

Ring sizes - MEASUREMENTS

How do I determine my ring size?

1. measure the inside diameter of another ring that fits the finger in question. Then read off the size from the table, corresponding to the diameter from our measurement.

2 Measure the circumference of the finger on which the ring will be worn. Then read off the size from the table, corresponding to the circumference from our measurement.

Please note that sizes are quoted to tenths of a millimetre, and a difference of one size may be virtually imperceptible and within the limits of measurement error.
