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.

A marquise lab grown diamond vintage cluster engagement ring from Signora Jewels.

A 1.00 ct, 10.38 × 5.14 mm marquise center is framed by 2 trillion lab grown diamonds and 8 round green gemstone accents. Side stones total approx. 0.22 ct combined; approx. 1.22 ct overall. center.

Made to order in 11 metals: silver, 10K/14K/18K gold (yellow, white, rose) and platinum.

Each metal color is shown in the photos. Choose your metal in the options on this page.

Signora Jewels sets the 10.38 × 5.14 mm marquise vertically, then places one trillion diamond on either side to widen the center without building a conventional halo. Eight small green rounds sit through the floral cluster work, breaking up the white stones with pinpoints of color. The sculpted leaves continue into the upper engagement ring shoulders.

The center sits above the surrounding clusters at roughly 6.0–6.5 mm high. Below the floral work, the shank narrows to about 1.60 mm wide and 1.60 mm thick, so most of the visual weight stays around the marquise rather than the lower band.

The trillions create a sharp transition from the long marquise into the shoulders, while the eight green rounds sit deeper in the floral pattern. From above, you see three larger geometric stones first; the smaller green accents appear as color between the leaves.

About Lab Grown Diamonds

The 10.38 mm marquise gives the center a long north-to-south profile, while the trillion side stones add width near its midpoint. For more on marquise proportions and diamond grading, see the diamond stone guide.

Metal, Care & Fit

Yellow and rose gold give the green accents and engraved leaf work stronger contrast. White gold and platinum put more visual emphasis on the marquise and trillion diamonds. Compare the choices in the metal guide. Use warm water, mild soap and a soft brush around the clustered stones and beneath the raised center.

FAQ

How many green accent stones are in this ring?
There are 8 round green gemstone accents. They sit through the floral shoulder clusters around the marquise and trillion diamonds.

What do the trillion diamonds do in this design?
Two trillion cut lab grown diamonds sit directly beside the marquise center. Their triangular outlines add width around the middle of the long center stone before the floral clusters begin.

How is the marquise center protected?
The marquise is held in an Eight-Prong setting with support around its pointed ends and sides. The surrounding clusters sit lower than the 10.38 × 5.14 mm center.

Will this ring sit flush with a straight band?
The floral clusters extend outward beside the elevated center, so a straight band can leave a small gap. A contoured band follows the cluster outline more closely.

Which metal brings out the green accents most clearly?
Yellow and rose gold create stronger color contrast around the 8 green rounds. White gold and platinum make the white diamond portions read brighter against the green accents.
