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.

The first thing you notice about this round lab grown diamond ring is the center—bright, open and lifted high enough to let the light reach every side.

Beneath that clean four-prong silhouette sits a hidden halo, visible in profile as a private circle of sparkle. Pavé-set diamond clusters continue along the shoulders, creating flashes at either side while leaving a polished stretch of band between the center and accents.

Shown with an approximately 2.56 ct center, the ring can be made with a round diamond from 1 to 4.5 ct. The basket and accent placement are proportioned around your selection so the finished ring keeps the same balanced, airy character.

Design highlights

Pavé shoulder clusters framed by sections of polished metal

The polished space on each shoulder is the quiet detail that makes the sparkle feel stronger—it separates the hidden halo from the side clusters, giving every diamond section room to catch the eye.

About Lab Grown Diamonds

A round brilliant is cut with 57–58 facets engineered to return light to the eye, creating the lively brilliance that makes it the most loved engagement-ring shape. The smaller round accents repeat that sparkle beneath the center and across the shoulders.

Every Signora diamond is lab grown—chemically, physically and optically identical to a mined diamond and graded on the same 4C scale. The difference is origin: grown rather than mined, with a documented source, no mining footprint and greater size or clarity for the budget.

Metal, Care & Fit

Choose Sterling Silver, 9K, 14K or 18K gold in yellow, white or rose, or naturally white Platinum. The photographed ring combines a warm yellow-gold shank with a white-tone setting; request a bespoke two-tone finish through our custom-design service.

Order in your known ring size; most metal options can be resized. Because the basket and hidden halo sit above the band, a curved or contoured wedding ring will usually create the closest bridal-stack fit. Clean with warm water, mild soap and a soft brush, then pat dry and store separately.

FAQ

Can I change the center diamond size?
Yes. Choose a round center from 1 to 4.5 ct, including the approximately 2.56 ct size shown. The four-prong basket is scaled to your selected diamond so the hidden halo and shoulder proportions remain balanced.

Where is the hidden halo on this engagement ring?
The halo sits directly beneath the center diamond rather than surrounding it from the top. It adds a ring of sparkle when the setting is viewed from the side while preserving the clean appearance of a round solitaire from above.

What is the total diamond weight of the pictured ring?
The pictured configuration contains approximately 2.85 ct across 45 diamonds. This includes the approximately 2.56 ct center and 44 round halo and shoulder accents totaling approximately 0.29 ct.

How are the center and accent diamonds set?
The center is secured in an elevated four-prong basket that leaves the sides open to light. The smaller diamonds are pavé and prong set through the hidden halo and clustered shoulder sections for concentrated sparkle.

Will a straight wedding band sit flush beside it?
The raised basket provides some space beneath the center, but the hidden halo and shoulder accents may still leave a small gap with a straight band. A curved or contoured wedding ring will usually trace the setting more closely.

Are the lab grown diamonds real diamonds?
Yes. Lab grown diamonds have the same carbon crystal structure, hardness and optical properties as mined diamonds and are graded using the same cut, color, clarity and carat standards. They are suitable for everyday engagement jewelry and will keep their sparkle with regular care.
