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 a lab-created ruby, and canary yellow a lab-created yellow sapphire. Each has the same crystal structure and optical properties as its mined counterpart, with vivid color and excellent value. These are genuine gemstones, not simulants like cubic zirconia.

It's also a meaningful birthstone gift: emerald (May), ruby (July), and yellow sapphire (September).

Metal, Care & Fit

Silver, 9K/14K/18K gold (yellow, white, rose) and platinum. Ruby and yellow sapphire are very hard (9 on the Mohs scale) and ideal for everyday wear. Emerald is a little softer (approximately 7.5–8 Mohs), so treat that color gently: avoid ultrasonic cleaning and hard knocks. Clean with warm water, mild soap and a soft brush. Ring size is selected on the storefront and is not a Shopify variant.

FAQ

What colors does this ring come in?
Three — emerald green, raspberry red and canary yellow. You choose one color; it is a single center stone, not all three together.

Are there any diamonds?
No. This is a clean solitaire design with one colored center gemstone and no accent diamonds.

Is the center stone a real gemstone?
Yes — the center is a lab-created emerald, ruby or yellow sapphire with the same crystal structure and optical properties as its mined counterpart. It is not cubic zirconia.

Which color is best for everyday wear?
Ruby and yellow sapphire are excellent for daily wear because they're 9 on the Mohs scale. Emerald can also be worn often with gentle care.

Is this a good engagement ring?
Yes. The classic solitaire setting gives the ring a meaningful engagement look with a colorful birthstone-style center.

Can I choose the metal?
Yes. Every ring is made to order in sterling silver, platinum, or solid 9K, 14K and 18K yellow, white or rose gold.

Will the color fade?
No. The color is part of the crystal itself and remains vibrant with normal wear.

How is it shipped?
