How to Measure Your Finger

Choose Your Finger
Decide which finger and hand you will wear your ring on.
Measure the Circumference
Wrap a piece of string or a thin measuring tape around the base of your finger. Make sure it fits snugly without feeling tight, and mark where the ends meet.
Find Your Size
Lay the string flat against a ruler and measure its length in centimeters. Compare that number with our size chart to find your Moissan ring size.

Tip: Measure your finger at the end of the day, when it is at its most natural size. If you fall between two sizes, we recommend choosing the larger one.

Two stones, one rhythm.
The Duet Tennis Bracelet pairs luminous moissanites with meticulously cut lab-grown emeralds, rubies, or sapphires in a repeating composition of color and brilliance. A contemporary interpretation of the classic tennis bracelet, each colorway creates a distinctive dialogue between vivid gemstones and light.
