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 cut lab grown diamond Hidden Halo engagement ring with vintage leaf shoulders from Signora Jewels.

A 7.8 × 5.5 mm oval center weighing approx. 1.00 ct, with a concealed round diamond halo of 0.08 ct and marquise-and-round shoulder diamonds totaling 0.17 ct. Approx. 1.25 ct combined.

Made to order in 11 metals: silver, 10K/14K/18K gold (yellow, white, rose) and platinum.

Choose your metal and color from the options on this page. The oval center is fixed at approximately 1.00 ct.

Look at the little eye-shaped openings on either side of the center. Signora Jewels sets a 7.8 × 5.5 mm oval above shoulders worked with tiny gold beads and marquise diamonds, each pointed accent sitting inside its own leaf-shaped outline. The center is held by curved prongs, with no visible ring of diamonds surrounding it from above.

Beneath the oval, approximately 16–18 small round diamonds form a hidden halo weighing 0.08 ct. Another 0.17 ct sits across the decorated shoulders, including two marquise diamonds and 10–14 rounds. The reference center weighs 1.00 ct, bringing the combined diamond weight to 1.25 ct.

About Lab Grown Diamonds

The oval center has a longer outline than a round brilliant, with rounded ends and facets extending along its length. The marquise shoulder diamonds echo that elongated shape on a smaller scale, while the round brilliant accents add closely spaced reflections beneath the center and through the leaf motifs. All diamonds are lab grown with F color and VS1 clarity specifications. Learn more in our diamond and stone guide.

Metal, Care & Fit

Choose silver, 10K, 14K or 18K yellow, white or rose gold, or platinum. The milgrain borders and hidden halo have small recessed spaces that collect residue, so clean with warm water, mild soap and a soft brush. Work gently beneath the oval basket and around the marquise shoulder settings. Remove the ring before heavy lifting or activities that place pressure on the raised center.

FAQ

Is the halo visible when looking directly at the ring?
No. The hidden halo sits beneath the oval center rather than forming a diamond border around its face. It is seen more clearly when the ring turns to the side.

Are the larger shoulder accents marquise diamonds?
Yes. Two marquise cut diamonds sit inside pointed, eye-shaped shoulder motifs. Additional round brilliant accents surround those motifs, bringing the shoulder diamond weight to approximately 0.17 ct.

Are the beaded borders made from diamonds?
No. The fine beads outlining the leaf-shaped shoulders are milgrain metalwork. The stones are separately set marquise and round brilliant diamonds.

How wide is the lower band?
The polished lower shank measures approximately 2.80 mm wide. The decorative shoulder section widens to around 3.5–4.2 mm before meeting the center basket.

How should I clean the hidden halo?
Use mild soap, warm water and a soft brush, working carefully beneath the oval center to reach the approximately 16–18 small halo diamonds. Rinse thoroughly and dry with a lint-free cloth.
