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 princess lab grown diamond engagement ring brings together sharp geometric beauty and exceptional brilliance. This design centers a perfectly proportioned princess-cut diamond in a classic solitaire setting, creating a look that feels both modern and timeless.

Beneath the center stone sits a hidden halo of round lab grown diamonds. From above, the ring appears as a clean solitaire, while side angles reveal a discreet circle of sparkle that adds depth and light without changing the elegant profile.

Made to order in your chosen center size and metal, this ring is designed for everyday comfort while showcasing the crisp lines and fire that make the princess cut one of the most loved engagement diamond shapes.

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, channel, or pavé settings that frame its straight lines.

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 traceable and efficient, you get a larger, cleaner stone for your budget with a documented origin and no mining footprint.

FAQ

Can I change the center stone size?
Yes. Center sizes from 1 CT to 4.5 CT are available, and the setting is scaled to suit the stone you choose.

What is a hidden halo?
A hidden halo is a circle of small diamonds positioned beneath the center stone. It adds sparkle from side angles while preserving the clean solitaire appearance from above.

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

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 4C scale.

Will a lab grown diamond last?
Yes. Lab grown diamonds rank 10 on the Mohs hardness scale and are suitable for a lifetime of daily wear.
