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 Asscher cut lab grown diamond halo engagement ring from Signora Jewels.

The reference ring features a 5.50 × 5.50 mm Asscher cut center diamond of approximately 1.00 ct surrounded by a double halo of 34 round diamonds and 40 micro pavé diamonds along the split shank, adding approximately 0.47 ct of accent diamonds.

Made to order in 11 metals: Silver, 9K, 14K and 18K Yellow, White and Rose Gold, plus Platinum.

Each metal color shown in the gallery represents the same design. Select your preferred metal and center diamond weight using the options above.

The Asscher cut is all about clean geometry. Its broad step facets create crisp flashes of light that move across the stone instead of scattering sparkle in every direction. Signora Jewels surrounds that square outline with a matching double halo, giving the center more presence while keeping its architectural shape intact.

The split shoulders taper naturally into a slim band, keeping the ring comfortable while drawing the eye toward the center. A four-prong basket rises from an open gallery so light reaches the pavilion from beneath, while the micro pavé shoulders continue the sparkle down each side without overwhelming the Asscher diamond.

Design Highlights

Customizable Asscher cut center diamond from 1 to 4.5 ct
Square double halo surrounding the center stone
34 round brilliant halo diamonds
40 round brilliant micro pavé shoulder diamonds
Four-prong basket with open gallery
Split shank design available in eleven precious metals

The double halo stays close to the center stone rather than spreading outward. It preserves the sharp corners that make an Asscher cut distinctive while adding another layer of brilliance from every viewing angle.

FAQ

Why choose an Asscher cut?
An Asscher cut produces broad flashes of light through step facets, creating a crisp geometric appearance that suits halo designs particularly well.

Does the double halo make the center diamond look larger?
Yes. The closely fitted double halo increases the visual spread of the center stone while maintaining the square outline of the Asscher cut.

Can I choose a larger center diamond later?
This design is built as a customizable ring, allowing you to select your preferred center diamond size before production begins.

How should I clean the halo and pavé diamonds?
Use warm water, mild soap and a soft brush to clean around the halo and between the pavé settings, then rinse thoroughly and dry with a lint-free cloth.
