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 round lab grown diamond crossover engagement ring from Signora Jewels.

The fixed design holds a 1.20 ct round center measuring approx. 6.90 mm, with 78 round accents totaling approx. 0.708 ct.

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

This is a fixed-center ring with a 1.20 ct round diamond. Check the ring size guide before ordering.

Signora Jewels builds this ring around two diamond-set rails that cross beneath the center and separate again at the shoulders. The 6.90 mm round sits forward in four broad prongs, while the curved upper rail draws light toward it from both sides.

The lower pavé line follows the finger instead of stopping abruptly at the head. Two larger round accents mark the crossover points, and the plain lower shank keeps the inside smooth where the ring meets the neighboring fingers.

The profile rises enough to let light enter beneath the center, but the crossover shoulders brace the basket from both sides. Review the proportions in our engagement ring guide.

From the front, the two rails frame the center without forming a halo. Turn the ring slightly and the separate pavé paths become visible, with small flashes running around the shoulder instead of sitting in one straight row.

About Lab Grown Diamonds

Lab grown diamonds have the same carbon crystal structure, hardness and optical properties as mined diamonds. The round center returns light in tight flashes, while the smaller shoulder stones create a finer line of sparkle. Read more in our lab grown diamond guide.

Metal, Care & Fit

Choose silver, 9K, 14K or 18K gold in yellow, white or rose, or platinum. The reference size is US 8. Clean beneath the center basket and between the crossover rails with warm water, mild soap and a soft brush. Rinse well, dry fully and remove the ring before swimming, lifting weights or applying lotion.

FAQ

Is the 1.20 ct center diamond included?
Yes. The fixed design includes one 1.20 ct round lab grown diamond center measuring approx. 6.90 mm.

What is the total diamond weight?
The total diamond weight is approx. 1.908 ct, made from the 1.20 ct center and approx. 0.708 ct of round accents.

How many accent diamonds are set in the ring?
The ring contains 78 round accent diamonds across the crossover shoulders and adjoining pavé rows.

Is this ring customizable by center carat?
No. This is a fixed-center design with the 1.20 ct round diamond included as specified.

How does a crossover ring compare with a straight pavé solitaire?
A crossover ring uses intersecting shoulder lines to frame the center, while a straight pavé solitaire carries its accent diamonds along one continuous row.

What is the difference between 9K and 18K gold?
9K gold is harder and more resistant to surface wear, while 18K gold contains more pure gold and has a richer color.

Can this ring be resized?
Yes. The plain lower shank allows most gold and platinum versions to be resized by a qualified jeweler.
