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 halo engagement ring from Signora Jewels.

The reference design carries a 9.10 × 6.70 mm oval brilliant center diamond of approximately 1.44 ct, framed by 42 round halo diamonds and 24 micro pavé diamonds totaling approximately 0.43 ct.

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

Each metal color shown represents the same design. Select your preferred metal and center diamond weight from the available options.

The oval halo follows the outline of the center stone closely, making the diamond appear larger while preserving its elongated proportions. Signora Jewels builds each ring around your selected center size so the overall balance remains consistent across every option.

The cathedral shoulders lift the basket above the band, allowing light to enter through the open gallery beneath the center diamond. Micro pavé diamonds continue across the shoulders, adding brightness without taking attention away from the oval centerpiece.

Design Highlights

Customizable oval center diamond from 1–4.5 ct
42 round brilliant halo diamonds
24 micro pavé shoulder diamonds
Four-prong cathedral basket
Open gallery for enhanced light return
Available in eleven precious metal options

The slim oval halo hugs the center stone instead of sitting wide around it. From a normal viewing distance the eye reads one continuous oval shape with added brilliance around the edges, giving the center greater visual impact.

FAQ

Does the oval halo make the center diamond appear larger?
Yes. The halo closely follows the outline of the oval center, increasing its visual spread while maintaining its elegant proportions.

Why is the basket raised on cathedral shoulders?
The cathedral shoulders support the basket while allowing more light beneath the center diamond through the open gallery.

Can I select a larger center diamond?
Yes. This ring is made to order with customizable center diamond sizes from 1 ct through 4.5 ct.

How should I clean the halo and pavé diamonds?
Use warm water, mild soap and a soft brush to remove buildup around the halo and between the pavé settings.
