To find your ring size, we recommend taking a piece of string and wrapping it around your finger. Hold the string around your finger as tight as you would like your ring to be, marking with a pen the point at which the end of the string lands on itself. Then, remove the string and measure the length between your mark and the end of the string with a ruler or tape measure.

With your measurement, find the corresponding size on our chart below.

Tips for the best fit:
DO measure the exact finger on which you would like to wear your ring. Every finger is different!
DON’T measure your ring size when you’re hot or cold, temperature affects the size of your finger.
DO make sure the string can move easily over the entire length of your finger.

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.

Carat
How big your diamond is. The physical weight of the diamond.

Color
This refers to how “white” the diamond appears. We use only the highest grades in our Liberté collection: G, F, E, and D—with D representing the whitest color.

Cut
The shape of the diamond—which determines how brilliantly it sparkles and helps create the ring's overall aesthetic.

Clarity
Clarity represents how transparent the diamond appears based on the number of inclusions.
Our diamonds range from VS2 (“Very Slightly Included”) to VVS1 (Very Very Slightly Included”) among the highest on the grading scale.
