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.

Sharp lines meet flowing sparkle in this princess lab grown diamond engagement ring, where a crisp square center rises above a hidden halo and softly twisting shoulders.

The split shank crosses beneath the center in an airy, ribbon-like motion. Pavé-set round diamonds follow one side of each twist, while polished metal creates contrast and keeps the design from feeling overly busy. From the side, the hidden halo adds another line of light beneath the princess diamond.

Shown with an approximately 2.42 ct center, the ring can be made with a princess diamond from 1 to 4.5 ct. The four-prong basket and surrounding details are proportioned around your selected stone before the ring is crafted to order.

About Lab Grown Diamonds

A princess diamond is a square brilliant with crisp corners and sharp, high-contrast sparkle. Its geometric outline gives this ring a modern focal point, while the round hidden-halo and shoulder diamonds add a softer, more fluid brilliance around it.

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 more size or clarity available 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 shows a yellow-gold shank with contrasting white-tone center prongs; a specific two-tone finish may be requested through our custom-design service.

Order in your known ring size; most metal options can be resized. The raised basket and twisting shoulders may leave a small space beside a straight wedding band, so a curved or contoured band will usually create the closest fit. Clean with warm water, mild soap and a soft brush, then pat dry and store separately.

FAQ

Can I choose a different princess diamond size?
Yes. Select a princess center from 1 to 4.5 ct, including the approximately 2.42 ct size shown. The basket and hidden halo are scaled to keep the setting balanced around your chosen diamond.

Where is the hidden halo positioned?
The halo sits directly beneath the princess center, so the ring looks clean and center-focused from above. From the side, the small round diamonds create a bright line around the base of the basket.

How are the princess diamond’s corners protected?
The center is secured by four substantial corner prongs positioned over the vulnerable points of the princess cut. This protects the corners while leaving the sides open so light can enter the diamond.

What is the total diamond weight of the ring shown?
The pictured configuration contains approximately 2.68 ct across 35 lab grown diamonds. That includes the approximately 2.42 ct princess center and 34 round accent diamonds totaling approximately 0.26 ct.

Is the twisted band fully covered in diamonds?
No. The design intentionally combines pavé-set sections with smooth, high-polish ribbons. That contrast makes the twist easier to see and gives the ring sparkle without losing its sculptural shape.

Will this ring sit flush with a wedding band?
The elevated center provides some clearance, but the crossover shoulders may create a small space beside a straight band. A curved or custom-contoured wedding ring will usually follow the setting more closely.
