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.

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

A 7.64 × 6.11 mm oval center of approx. 1.08 ct sits inside 12 round halo diamonds, with another 18 rounds continuing along the band. Approx. 1.66 ct total.

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

Each metal color is shown in the photos. Choose your metal from the options on this page.

Signora Jewels sets the 7.64 × 6.11 mm oval inside a close ring of twelve round diamonds. Four prongs grip the center at its curved shoulders, leaving the top and bottom open so the oval keeps its full length.

The halo sits on a raised gallery above eighteen smaller rounds along the band. Those 1.40 mm stones continue the sparkle past the center without adding bulk under the finger, while the open space beneath the basket gives a soft brush room to reach the pavilion.

The halo does more than add another row of diamonds. Its twelve larger rounds follow the oval outline closely, making the center read wider while preserving its elongated shape.

About Lab Grown Diamonds

The oval center gives more visible length than a round diamond of similar weight. Its curved perimeter also avoids exposed points, while the surrounding round diamonds break light into smaller flashes around the broad center stone.

Metal, Care & Fit

White gold and platinum blend with the halo prongs, making the diamonds read as one continuous outline. Yellow and rose gold leave a warmer border visible beneath the stones. Clean under the raised gallery with warm water, mild soap and a soft brush, paying attention to the spaces between the halo diamonds.

FAQ

How does the halo change the appearance of the oval center?
The 12 round halo diamonds add width around the 7.64 × 6.11 mm oval. Their close placement makes the center look larger without hiding its elongated outline.

Does the oval sit high above the band?
The oval sits on a raised halo gallery above the diamond band. This separates the center from the 1.40 mm band stones and leaves room beneath the basket for cleaning.

Which metal makes the halo look most continuous?
White gold and platinum allow the small prongs to blend with the round diamonds. Yellow and rose gold create a visible outline beneath the halo and band.

How should I clean the halo and diamond band?
A soft brush reaches between the 12 halo diamonds and beneath the center basket. Brush gently from the underside so lotion does not remain around the shared prongs holding the 18 band stones.
