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

A fixed round Lab Grown Diamond hidden halo engagement ring from Signora Jewels.

The ring includes a 1.170 ct, 6.80 mm round center and 22 hidden-halo diamonds totaling approx. 0.066 ct.

Twenty-three diamonds total approx. 1.236 ct in a four-prong center basket with a plain polished shank.

Made to order in silver, 9K/14K/18K yellow, white or rose gold, and platinum.

Made to order — select your metal above. Change the center size, basket height or halo layout through our custom jewelry service.

Signora Jewels sets the 6.80 mm round center above a narrow ring of twenty-two 0.80 mm diamonds. From the top, the design reads as a clean solitaire because the halo sits beneath the center rather than around its outer edge.

Four prongs hold the diamond while the hidden halo circles the lower basket. Turn the ring sideways and the accents catch light below the girdle; face it forward and the plain shoulders keep the center unobstructed.

The polished shank narrows as it reaches the basket, then widens through the lower band. Nothing is set along the shoulders, so there are fewer raised edges where the ring meets clothing.

The hidden halo changes the side view without crowding the top. Its diamonds sit below the center, adding a narrow ring of light around the basket while the round outline remains clear.

About Lab Grown Diamonds

A round brilliant uses 57–58 facets to return light toward the eye. Here, the 6.80 mm center provides the main flash while the smaller hidden-halo diamonds brighten the basket when the ring tilts.

Lab grown diamonds have the same carbon crystal structure, hardness and optical properties as mined diamonds. They are graded using the same cut, color, clarity and carat standards.

Metal, Care & Fit

Choose silver, 9K/14K/18K gold in yellow, white or rose, or platinum. 9K contains more strengthening alloy, while 18K contains more gold and has richer color; compare every option in the metal guide.

Order in your known size. The plain lower shank allows easier sizing than a fully pavé band, but an accurate starting size keeps the basket upright; use the ring size and fit guide. Clean beneath the center and around the hidden halo with warm water, mild soap and a soft brush.

FAQ

Is the center diamond included?
Yes. The ring includes one fixed 1.170 ct round Lab Grown Diamond center measuring approximately 6.80 mm. The center carat is not a variant on this design.

Where is the hidden halo positioned?
The hidden halo sits beneath the center diamond around the lower basket. It appears from the side and angled views while remaining largely concealed from directly above.

How many diamonds are in the hidden halo?
The hidden halo contains 22 round diamonds measuring approximately 0.80 mm each. Together they weigh approx. 0.066 ct.

What is the total diamond weight?
The ring contains approx. 1.236 ct across 23 diamonds. That total combines the 1.170 ct center with the 0.066 ct hidden halo.

How is the center diamond held?
The round center is held in a four-prong basket. The prongs leave most of the diamond’s circular edge visible and provide access beneath the stone for cleaning.

What is the difference between a hidden halo and a standard halo?
A hidden halo sits below the center and is seen mainly from the side, while a standard halo surrounds the center in the top view. This setting keeps the face of the ring looking like a solitaire.

What is the difference between 9K and 18K gold?
9K gold has more strengthening alloy and a harder surface, while 18K contains more gold and has richer color. Both are solid gold choices for an engagement ring.

What is included in the finished ring?
Signora Jewels includes the fixed center diamond, all 22 hidden-halo accents and the selected made-to-order metal in the completed ring.
