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 radiant center is secured by four rounded prongs that leave the clipped corners visible while allowing light to enter from every direction. On each side, tapered trapezoid diamonds create a smooth transition into the polished band, giving the ring a balanced three-stone profile with crisp architectural lines.

The approximately 1.00 ct radiant center combines the brilliance of a round diamond with the elegant outline of an emerald cut. The matching trapezoid side diamonds add width across the finger without competing with the center, creating approximately 1.40 carats of lab grown diamonds in a refined engagement ring that is comfortable enough for daily wear.

Every ring is individually crafted by Signora Jewels. Each lab grown diamond is carefully matched, hand set and polished before the finished piece is inspected to ensure exceptional craftsmanship and lasting beauty.

About Lab Grown Diamonds

Radiant cut diamonds combine trimmed corners with brilliant faceting, producing lively sparkle while maintaining a sophisticated rectangular outline. The trapezoid side diamonds complement the center by adding broad flashes of light and balanced proportions.

Every Signora lab grown diamond is chemically, physically and optically identical to a mined diamond and graded using the same international standards. You receive the beauty and durability of a real diamond with a documented origin and no mining footprint.

Metal, Care & Fit

Choose from Sterling Silver, 9K, 14K or 18K Gold in Yellow, White or Rose, or Platinum. Clean your ring using warm water, mild soap and a soft brush, then dry with a lint-free cloth. Store it separately to help preserve its polished finish.
