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 lab grown diamond four-prong engagement ring from Signora Jewels.

The reference center is a 2.00 ct princess cut measuring approximately 7.0 × 7.0 mm, secured by four rounded corner prongs. Approximately 20–24 shoulder diamonds total 0.29 ct.

Made to order in 10K, 14K and 18K gold, available in yellow, white and rose gold.

Approximately 2.29 ct reference total diamond weight, with a pavé-set upper shank and no halo.

Made to order in your chosen gold color and purity, with a princess-cut center from 1 to 4.5 ct.

Signora Jewels sets a 7.0 × 7.0 mm princess-cut reference diamond between four rounded corner prongs in this engagement ring. The square outline stays fully visible between the claws, without a halo around its edges.

Approximately 20–24 round diamonds continue along both shoulders, adding 0.29 ct outside the center. The diamond-set section widens slightly near the head before narrowing into a polished 2.00 mm lower shank.

The princess cut's straight edges and pointed corners contrast with the smaller round diamonds along the band. Four separate claws hold those corners, while the pavé carries the light outward before ending at the plain lower shank.

About Lab Grown Diamonds

The princess cut has a square outline with pointed corners and closely arranged brilliant facets. The round shoulder diamonds add smaller reflections along the band. Read our diamond stone guide to compare the two cuts.

Metal, Care & Fit

Choose yellow, white or rose gold in 10K, 14K or 18K purity. Keep the four corner claws clear of hard knocks and gently brush between the small shoulder diamonds. Follow our jewelry care guide for cleaning instructions.

FAQ

How are the four corners of the princess-cut diamond protected?
Four rounded metal prongs secure the diamond at its corners. The 7.0 × 7.0 mm reference center remains exposed along its straight sides, so remove the ring for lifting or activities that could knock the setting.

Does this princess-cut ring have a halo?
No. The center sits directly in a Four-Prong setting. Approximately 20–24 round accent diamonds run along the shoulders rather than surrounding the princess-cut center.

How much diamond weight is in the pavé shoulders?
The shoulders contain approximately 0.29 ct of round brilliant diamonds. Combined with the 2.00 ct reference center, the ring has approximately 2.29 ct total diamond weight.

Can a straight wedding band sit flush against this ring?
The reference setting height is approximately 6.8–7.3 mm, with shoulders measuring 2.10–2.30 mm wide. These measurements do not establish clearance beneath the head, so compare the completed setting with the intended companion band.

How should I clean the corner prongs and pavé shoulders?
Use warm water, mild soap and a soft brush around the four corner claws and between the small round shoulder diamonds. Rinse thoroughly and pat dry without dragging fabric through the settings.
