1.0CT Marquise Cut Unique Cluster Lab Grown Diamond Engagement Ring Proposal Ring
✥ "It's very important to have your perfect ring size when you purchase your diamond rings."
Method 1: Measure a Ring
-
Find a ring that fits comfortably on the intended finger.
-
Measure the internal diameter of the ring in millimeters (mm) using a ruler or measuring tape.
-
Find your size using our size chart above.
Method 2: Measure your Finger
-
Cut a piece of string to a length of 10cm.
-
Wrap the string comfortably around your finger where the ring should sit - this should not be pulled tight.
-
Use a pen to mark the overlapping parts of the string.
-
Lay the string out flat and measure the distance between the two marked points (in millimeters).
-
Find your size using our size chart above.

Expert tips
-
Measure the correct finger - the same finger on the opposite hand will often be a different size.
-
Don’t have a string? A folded strip of paper will suffice.
-
Always measure twice.
-
Measuring in the afternoon when your hands are warm will give you the most accurate result.
-
Oversized rings may require a larger size to ensure correct fitment. Contact Customer Service if you’re unsure.
Hint: You can also download and print our Ring Size Guide to directly measure your ring.
