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-cut center diamond changes the way light moves compared with a round stone. The crisp corners and straight edges create bright flashes that feel clean and modern, while two rows of surrounding diamonds make the center appear even larger from the top view. Signora Jewels builds each ring to order after you choose the center size and metal.

The four-prong head keeps the square outline open so light reaches the center from every side. A pavé band continues the sparkle onto the finger without making the ring feel heavy, and the closely set halos create a bright frame around the princess diamond instead of overpowering it.

Choose your preferred center diamond from 1 to 4.5 carats together with your choice of 11 precious metal options. Every ring is individually crafted by Signora Jewels rather than taken from stock.

The double halo is what gives this design its personality. From normal viewing distance you notice one continuous frame of light around the princess center, while up close the individual diamonds add depth that a single halo cannot create.

About Lab Grown Diamonds

The princess cut combines a square outline with brilliant faceting that creates bright flashes of light across the table while preserving the clean geometry that makes this shape distinctive.

Lab grown diamonds are chemically, physically and optically identical to mined diamonds. They are graded using the same 4Cs, have the same hardness of 10 on the Mohs scale, and provide the same brilliance while offering a documented origin and no mining footprint.

Metal, Care & Fit

Sterling Silver offers bright everyday value. Solid 9K, 14K and 18K gold increase in gold content and richness of color, while platinum is naturally white, dense and hypoallergenic. Order your normal ring size, clean with warm water, mild soap and a soft brush, and store the ring separately to keep the finish looking its best.

FAQ

Can I choose a different center diamond size?
Yes. This design is available from 1 ct through 4.5 ct, and the ring is built around the center size you select.

Are the accent diamonds included?
Yes. Every ring includes all 62 lab grown accent diamonds exactly as shown.

Are lab grown diamonds real diamonds?
Yes. They have the same chemical composition, hardness and brilliance as mined diamonds and are graded using the same standards.

Why choose a princess cut instead of a round diamond?
A princess cut has crisp square corners and bold flashes of light, while a round diamond produces a softer circular sparkle. The choice comes down to the look you prefer.

Can this ring be resized?
Most precious metal versions can be resized after purchase. Contact Signora Jewels if you need sizing assistance.

What metals are available?
Choose from Sterling Silver, 9K, 14K and 18K Yellow, White or Rose Gold, and Platinum.
