Rings sizing guides

Our team of diamond jewelry experts have put together a complete ring size guide to help you measuring your fingers at home which includes a ring size chart, printable ring sizer, and tips that you should follow to find your perfect fit.

The first tip we would like you to follow is to measure your finger at the end of the day. Do not measure your finger when it is hot or cold. As you probably know, your two hands slightly differ in size and consequently, a ring on a finger on your left hand will not be the same fit on the same finger on your right hand.

Once you found the chosen size, make sure to leave enough room for the ring to entirely and easily pass along the length of your finger.

If you hesitate between two sizes, we always recommend you picking the larger size.

How to measure your ring size at home?

The easier way of measuring your finger size is to use a tape measure to measure the circumference of your finger in millimeters (mm). This measurement will correspond to the size of the ring.

If you don’t have a tape measurer at home, then you could wrap a string or a paper around the base of your finger, then measure the string or the paper with a ruler.

Another tip is to measure the inside of another ring that fits your finger with a tape measure. Remember that all our styles will affect the choice of the size.

If you hesitate in any way, please book an appointment with our bespoke concierge who will offer a personalized shopping experience.
