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 Our Lab-Created Gemstones

The center is a lab-created gemstone: Emerald Green is a Lab Created Emerald, Raspberry Red is a Lab Created Ruby, and Canary Yellow is a Lab Created Yellow Sapphire. Each has the same crystal structure and optical properties as its mined counterpart, with vivid color and strong value.

Emerald is the May birthstone, Ruby is the July birthstone, and Yellow Sapphire is the September birthstone.

Metal, Care & Fit

Available in sterling silver, platinum, and solid 9K, 14K or 18K yellow, white and rose gold. Ring size is selected on the storefront and is not a separate variant.

Ruby and yellow sapphire are durable at 9 Mohs and suitable for everyday wear. Emerald is softer at about 7.5–8 Mohs, so clean gently with warm water, mild soap and a soft cloth. Avoid ultrasonic and steam cleaning for the emerald option.
