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.

At a glance

An oval lab grown diamond hidden halo engagement ring from Signora Jewels.

The ring shown carries a 9.20 × 6.80 mm oval brilliant of approximately 1.50 ct in a four-prong cathedral basket, accented by 18 hidden halo diamonds and 26 micro pavé diamonds for approximately 0.48 ct of additional sparkle.

Made to order in 11 metals: silver, 9K/14K/18K gold (yellow, white and rose) and platinum.

Each metal color is shown in the photos—choose your preferred metal and center diamond weight from the options on this page.

The hidden halo stays out of sight from the top, leaving the oval center to do the talking. From the side, the extra row of diamonds catches light beneath the basket, giving the ring a brighter profile without changing its clean solitaire appearance. Signora Jewels builds every ring to order around your selected center size.

The cathedral shoulders lift the basket into the center of the ring while adding support beneath it. A 2.20 mm shoulder flows into a slim 2.00 mm band, keeping the ring balanced while the open gallery lets light pass beneath the oval diamond.

About Lab Grown Diamonds

Metal, Care & Fit

FAQ

Does the hidden halo change the look from the top?
No. The hidden halo sits beneath the center diamond, so the ring keeps the appearance of a classic oval solitaire until viewed from the side.

Why use a cathedral setting?
The cathedral shoulders support the basket from beneath while lifting the center diamond into a balanced position above the band.

Can this ring be worn with a wedding band?
Yes. The straight micro pavé shank pairs well with many traditional wedding bands, although the exact fit depends on the profile of the band you choose.

Which metal best complements this design?
White gold and platinum emphasize the hidden halo and diamond brightness, while yellow and rose gold create stronger contrast around the oval center.

How should I clean the pavé band?
Use a soft brush to clean between the pavé settings where everyday residue collects. Avoid abrasive cleaners that can dull the polished finish.
