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.

AT A GLANCE

A three stone emerald lab grown diamond engagement ring from Signora Jewels.

The photos show an approximately 2.75 ct emerald-cut center diamond with two radiant-cut side diamonds totaling approximately 1.30 ct, all secured in four-prong settings. IGI certification is included.

Made to order in 11 metals: Sterling Silver, 9K, 14K and 18K gold in yellow, white or rose, plus Platinum.

Made to order — the price updates with your selection. Want something fully custom? Customize your jewelry here.

The long step facets of the emerald-cut center throw broad flashes instead of glitter, while the radiant-cut side diamonds brighten the shoulders with lively sparkle. The contrast between the two cuts gives the ring its character from the first glance.

The center sits slightly higher than the side stones in open four-prong baskets, allowing light to enter from every direction. The shoulders flow cleanly into the setting without adding bulk, keeping the focus on the three diamonds across the finger.

Signora Jewels makes every ring to order in your chosen center size and metal, so the proportions stay balanced across every carat option.

The mix of step-cut and brilliant-cut diamonds is what makes this ring different. The emerald center gives slow, mirror-like flashes, while the radiant sides add crisp sparkle that frames the center without competing with it.

About Lab Grown Diamonds

Emerald-cut diamonds are known for their long step facets and hall-of-mirrors effect. Instead of rapid sparkle, they produce broad flashes of light that highlight clarity and clean geometry.

Every lab grown diamond from Signora Jewels is chemically, physically and optically identical to a mined diamond and graded using the same 4Cs. They offer the same lifetime durability with a documented origin and no mining footprint.

Metal, Care & Fit

Sterling Silver, 9K, 14K and 18K gold in yellow, white and rose, plus Platinum are available. Order your usual ring size; most precious metals can be resized later if needed. Clean with warm water, mild soap and a soft brush, then dry with a lint-free cloth. Remove before swimming or applying lotions.

FAQ

Can I choose a different center diamond size?
Yes. This design is available with center diamonds from 1 to 4.5 carats, and the setting is built specifically for the size you select.

Why are the side diamonds radiant cut instead of emerald cut?
Radiant-cut side stones introduce extra sparkle beside the emerald-cut center. The combination creates contrast while keeping the center diamond visually dominant.

Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds have the same chemical composition, crystal structure, hardness and brilliance as mined diamonds and are graded using the same international standards.

What's the difference between 9K and 18K gold?
9K gold contains more alloy metals, making it harder for everyday wear. 18K gold has a richer gold color and higher gold content while remaining suitable for daily use.

Can this ring be resized?
Yes. Most precious metal versions can be resized after purchase. Contact us if you ever need sizing assistance.

Can I customize this design further?
Yes. Beyond the available center sizes and metals, Signora Jewels can create a fully bespoke version through our custom jewelry service.
