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 cushion Lab Grown Diamond triple-row engagement ring from Signora Jewels.

As shown: a 3.00 ct, 8.00 × 8.00 mm cushion center in a four-prong setting, with 42 round pavé accents totaling approx. 0.504 ct.

Forty-three Lab Grown Diamond stones total approx. 3.504 ct in the photographed configuration.

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

Made to order — the price updates with your selection. Change the center size, row spacing or pavé coverage through our custom jewelry service.

Signora Jewels sets the 8.00 × 8.00 mm cushion above a polished center band, then runs a diamond-set row along each side. The three bands stay separate near the head, giving the ring width without turning the shoulder into one solid block of metal.

Forty-two 1.40 mm rounds sit in U-cut settings across the outer rows. They catch light above and below the plain middle band, while four prongs leave the cushion’s rounded corners and broad face easy to read.

The lower shanks stack closely against the finger. From the side, the raised basket leaves space beneath the center and keeps the three rows visually distinct.

The contrast between the plain center band and the two pavé rows is the defining detail. One polished strip frames the cushion while the outer lines break into smaller flashes around it.

About Lab Grown Diamonds

A cushion cut combines rounded corners with broad brilliant facets, producing wider flashes than a round diamond. In this ring, the square outline sits above two pavé rows that add tighter points of light around the center.

Lab grown diamonds have the same carbon crystal structure, hardness and optical properties as mined diamonds. They are graded using the same cut, color, clarity and carat standards.

Metal, Care & Fit

Choose silver, 9K/14K/18K gold in yellow, white or rose, or platinum. 9K contains more strengthening alloy for daily wear, while 18K has higher gold content and richer color; compare them in the metal guide.

Order in your known size. The three-row shank covers more of the finger than a single band, so accurate sizing matters; use the ring size and fit guide. Clean between the rows and beneath the basket with warm water, mild soap and a soft brush.

FAQ

Can I choose another center diamond size?
Yes. The cushion center is available from 1 to 4.5 ct, and the basket and metal weight scale to the selected carat. The photographed configuration uses an approx. 3.00 ct center measuring 8.00 × 8.00 mm.

How many pavé diamonds are set into the ring?
The two outer rows contain 42 round pavé diamonds totaling approximately 0.504 ct. Each accent measures approximately 1.40 mm and sits in a U-cut setting.

How is the cushion center held?
The cushion center is secured by four prongs placed near its rounded corners. This leaves the broad sides visible and keeps the pavilion open beneath the stone.

Are the three bands separate?
The upper shank is arranged as three close rows: a polished center band and two diamond-set outer rows. They sit together as one ring and remain visually separated near the center setting.

Will a wedding band sit beside this ring?
A straight wedding band will sit beside the lower shank, though the three-row width creates a broader stack on the finger. A thin plain band or gently contoured band gives the closest pairing.

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

How does a cushion cut compare with a round diamond?
A cushion cut has a square outline with rounded corners and broader flashes, while a round diamond produces a more even pattern of smaller scintillation. Signora Jewels uses the cushion outline here to fill the space between the three band rows.
