Method 1: Measure a Ring
-
Find a ring that fits comfortably on the intended finger.
-
Measure the internal diameter (mm) of the ring, using a ruler or measuring tape.
-
Find your size using our size chart above.
Method 2: Measure your Finger
-
Cut a piece 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 string between the two marked points (mm).
-
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 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 visit our Ring Size Guide to directly measure your ring.

Lab Grown FAQ's
What are lab-grown diamonds?
Lab-grown diamonds are real diamonds created in a controlled environment, replicating the natural process that forms mined diamonds.
How are lab-grown diamonds made?
They are created using advanced techniques like High-Pressure High-Temperature (HPHT) or Chemical Vapor Deposition (CVD), which mimic the conditions under which natural diamonds form.
Are lab-grown diamonds ethical and eco-friendly?
Lab-grown diamonds are a sustainable choice as they avoid the environmental and ethical concerns associated with traditional diamond mining.
Are lab-grown diamonds cheaper than mined diamonds?
Yes, lab-grown diamonds typically cost 20-40% less than their mined counterparts while maintaining the same quality.
Can lab-grown diamonds be certified?
Absolutely! They are graded and certified by the same gemological institutes that certify mined diamonds, such as GIA or IGI.
Do lab-grown diamonds last as long as mined diamonds?
Yes, lab-grown diamonds are just as durable and will last a lifetime with proper care.
Can you tell the difference between lab-grown and mined diamonds?
No, even professional gemologists cannot tell the difference without specialized equipment.
