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.

AT A GLANCE
Signora Jewels custom engagement ring with a round lab grown diamond center and twenty mixed-shape accent diamonds.
Shown with a 2.50 ct round brilliant and approximately 1.504 ct of side diamonds for about 4.004 ct total.
Four-prong basket with tapered marquise, baguette, oval, pear and round side stones that narrow naturally toward the band.
Made to order by Signora Jewels in eleven precious metal options with customizable center diamond sizes.

The round center sits high enough to flood the stone with light while the shoulders taper toward it through five different diamond shapes instead of repeating a single cut. The mix of marquise, baguette, pear, oval and round diamonds creates changing flashes as the ring turns, giving the shoulders their own rhythm without taking attention away from the center.

Nothing about the profile feels bulky. The side stones narrow toward the shank so the ring stays balanced on the finger, while the open four-prong basket keeps the center bright from every angle. Signora Jewels builds each ring to order after you choose the center size and metal.

Design Highlights

Round brilliant center diamond customizable from 1 to 4.5 ct
Twenty mixed-shape accent lab grown diamonds
Approx. 1.504 ct side diamond weight as shown
Four-prong basket keeps the center open to light
Tapered shoulder design with marquise, baguette, oval, pear and round diamonds
Made to order in 11 precious metal options
Ideal for engagements and anniversaries

The shoulders are the signature detail. Instead of identical accent stones, each shape transitions into the next so the sparkle changes across the band rather than repeating the same pattern.

About Lab Grown Diamonds

Round brilliant diamonds are cut with 57–58 facets engineered to return light to the eye, making them the brightest and most popular diamond shape for engagement rings.

Every Signora Jewels diamond is lab grown—chemically, physically and optically identical to a mined diamond and graded on the same 4C scale. Choosing lab grown lets you enjoy a larger, cleaner diamond with a documented origin and no mining footprint.

Metal, Care & Fit

Sterling silver is bright and accessible. Solid 9K, 14K and 18K gold increase in gold content and color richness, while platinum is naturally white, dense and hypoallergenic. Order your usual ring size. Clean with warm water, mild soap and a soft brush, then store separately to keep the finish bright.

FAQ

Can I choose a different center diamond size?
Yes. This design is available with round center diamonds from 1 ct to 4.5 ct, and the setting is built specifically for the size you select.

How many diamonds are in the ring?
The ring shown contains twenty-one lab grown diamonds: one round center stone and twenty accent diamonds across the shoulders.

Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds have the same chemical composition, hardness and brilliance as mined diamonds and are graded using the same standards.

Why are several diamond shapes used on the shoulders?
The tapered arrangement blends marquise, baguette, oval, pear and round diamonds so the shoulders narrow naturally toward the center while producing different flashes of light as the ring moves.

What is the difference between 9K and 18K gold?
Both are solid gold. 9K is harder for everyday wear, while 18K contains more pure gold and has a richer color.

Can the ring be resized?
Yes. Most precious metal versions can be resized after purchase. Contact Signora Jewels if resizing is ever needed.

Is the ring made to order?
Yes. Signora Jewels crafts every ring after your metal and diamond selections are confirmed, ensuring the finished piece is built specifically for your order.
