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.

Choose your center diamond weight and metal from the options on this page.

The two green marquise stones sit close against the cushion diamond, one on either side. Signora Jewels pairs this 7.3 × 6.6 mm center with pointed emerald accents and small round diamonds, giving the setting a layered outline without a surrounding halo. Double-claw detailing grips the cushion's corners, while the raised gallery leaves the underside open.

The center weighs approximately 1.50 ct in the reference design. Both emerald gemstones total 0.08 ct, and approximately eight round brilliant diamonds add another 0.05 ct. Beyond the side stones, the gold shoulders are worked with open filigree, small cutouts and fine milgrain edges rather than continuous pavé rows.

About Lab Grown Diamonds

The cushion center has softened corners and brilliant-style facets, while the two pointed green emeralds create a contrast in both color and shape. The white accent diamonds add smaller reflections around the sides. The center and round accent diamonds are lab grown. See our diamond and stone guide for more about cut and diamond proportions.

Metal, Care & Fit

Choose silver, 10K, 14K or 18K yellow, white or rose gold, or platinum. The raised center basket and individually set marquise emeralds require care around fitted sleeves. Emerald gemstones need gentler cleaning than diamonds. Use a soft damp cloth and mild soap, and avoid steam, ultrasonic machines and harsh chemicals. Clean carefully around the filigree openings and milgrain borders without pressing against the pointed gemstone ends.

FAQ

Are the two green side stones emerald gemstones?
Yes. Two green marquise-cut emerald gemstones sit beside the cushion diamond, weighing approximately 0.04 ct each. They are separate from the white lab grown diamond accents.

How many diamonds are in this design?
Approximately nine diamonds are included: one cushion center and eight small round brilliant accents. Their combined reference weight is 1.55 ct, excluding the two emerald gemstones.

Does this ring have a halo?
No. The cushion center is held in a raised basket without a complete diamond halo. The accent diamonds and green emeralds are arranged along the sides of the center setting.

Can I choose a different cushion center weight?
Yes. The center diamond is selectable from 1 ct through 4.5 ct, including the reference 1.50 ct. The basket is made to suit the chosen center dimensions.

How should I protect the pointed emerald side stones?
Both marquise emeralds are held in individual prong settings beside the cushion center. Avoid direct impacts against their pointed ends, and clean them gently with a soft damp cloth rather than abrasive tools.
