Ring size guide

Lay a ring you own flat on the circle and slide until it sits just inside it — or set its inner diameter directly.

Measure the inside of a ring that already fits — inner edge to edge — with a ruler in mm, then set it below. No ring handy? Try Measure your finger.

Between sizes? Always choose the larger size. Fingers are slightly bigger in the evening — measure then for the best fit.

Method 1 — Use an existing ring

Find a ring that fits the intended finger comfortably.
Place it flat and measure the inner diameter (inside edge to inside edge) in mm.
Enter that measurement in the Measure a ring tab.

Method 2 — Wrap and measure

Wrap a thin strip of paper around the base of your finger.
Mark where it overlaps — measure that length in mm (your circumference).
Divide by 3.1416 (π) to get your diameter, then use the Measure a ring tab.

Tip: Middle finger sizes typically run half a size larger than the ring finger. If between sizes, go up. Measure in the evening — fingers are slightly larger then.

About Lab Grown Diamonds

Lab grown diamonds are real diamonds with the same chemical, physical, and optical properties as mined diamonds. They offer identical brilliance, durability, and beauty while providing exceptional value and a responsible alternative to traditionally mined stones.

The marquise cut is celebrated for its elegant pointed silhouette and elongated proportions. Its unique shape creates the appearance of a larger diamond while beautifully lengthening the look of the finger.
