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.

An oval Lab Grown Diamond split-shank engagement ring from Signora Jewels.

As shown: a 2.00 ct, 10.50 × 7.00 mm oval center in a four-prong setting, with 40 round accent diamonds totaling approx. 0.574 ct;

Made to order in 11 metals: silver, 9K/14K/18K gold in yellow, white or rose, and platinum.

Made to order — the price updates with your selection. Adjust the proportions, setting or accent layout through our custom jewelry service.

Signora Jewels builds this oval Lab Grown Diamond engagement ring around a 10.50 × 7.00 mm center, held at four points so the long outline stays open and easy to read.

The band separates beside the center into three close lines. Forty graduated rounds step down from 1.90 to 1.00 mm, filling the shoulders with light while the polished outer edges keep the ring from feeling crowded.

At US size 7, the shank narrows to approximately 1.55 mm at the base. The oval sits above the branching shoulders, giving a straight wedding band room to meet the ring with only a small gap.

Design highlights

The graduation does the shaping. Larger rounds sit nearest the oval, then reduce toward the band so the shoulder narrows without an abrupt break in sparkle.

About Lab Grown Diamonds

An oval brilliant carries the fire of a round diamond through an elongated outline. Its length covers more of the finger, while the rounded ends avoid the exposed point found on pear and marquise cuts.

Every diamond in this ring is lab grown, with the same carbon crystal structure, hardness and optical properties as a mined diamond. The stones are graded using the same cut, color, clarity and carat standards.

Metal, Care & Fit

Sterling silver is bright and accessible. 9K gold contains more strengthening alloy for daily wear, while 18K has richer gold color and a softer surface. Compare every option in the metal guide.

Order in your known US size. Because the upper shank divides into several diamond-set rows, accurate sizing matters more than on a plain band; use the ring size and fit guide. Clean with warm water, mild soap and a soft brush, then pat dry.

FAQ

Can I choose another center diamond size?
Yes. The oval center is available from 1 to 4.5 ct, and the head and metal weight scale to the selected carat. The photographed CAD uses an approx. 2.00 ct center measuring 10.50 × 7.00 mm.

How many accent diamonds are set into the shank?
The ring contains 40 round accent diamonds totaling approximately 0.574 ct as shown. Their sizes graduate from approximately 1.90 to 1.00 mm across the branching shoulders.

How is the oval center held?
The oval center is secured by four prongs positioned around its rounded outline. This leaves the sides exposed to light and keeps the elongated shape clear from above.

Will a wedding band sit beside this ring?
A straight wedding band sits close to the raised center and split shoulders, with a small gap depending on the band height. A gently contoured band gives the closest fit.

What is the difference between 9K and 18K gold?
9K gold has more strengthening alloy and a harder surface, while 18K contains more gold and has richer color. Both are solid gold and suitable for an engagement ring.

Are lab grown diamonds different from mined diamonds?
Lab grown diamonds have the same carbon structure, hardness and optical properties as mined diamonds; their origin is different. Signora Jewels supplies this ring only with Lab Grown Diamond stones.

Does the total diamond weight change with the center selection?
Yes. The photographed configuration totals approximately 2.574 ct, including a 2.00 ct center and 0.574 ct of accents. The final total changes when another center carat is selected.
