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 bold geometric silhouette meets classic simplicity in this princess cut lab grown diamond solitaire ring. The square center diamond is elevated above a clean high-polish band, allowing the stone's crisp faceting and brilliance to take center stage.

Four sculpted corner prongs secure the princess cut diamond while maintaining an open profile that lets light enter from multiple angles. The result is a bright, lively diamond presentation with a modern architectural feel.

Made to order in your preferred center size and precious metal, this solitaire is designed for those who appreciate clean lines, strong proportions, and timeless everyday wear.

About Lab Grown Diamonds

A princess is a square brilliant with crisp corners and sharp, high-contrast sparkle. It offers a contemporary edge and strong value per carat, and looks especially clean in solitaire settings that highlight its straight lines and geometric symmetry.

Every Signora Jewels diamond is grown in a controlled lab, producing a stone that is chemically, optically, and physically identical to a mined diamond. Because the supply chain is shorter and traceable, you can enjoy a larger, cleaner diamond for your budget with a documented origin and no mining footprint.

FAQ

Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds are chemically, physically, and optically identical to mined diamonds and are graded on the same standards.

What metals can I choose?
Silver, 9K / 14K / 18K gold in yellow, white or rose, and Platinum.

Is the center diamond included?
Yes. The listed configuration includes the princess cut lab grown diamond shown in the specifications.
