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 hidden halo engagement ring from Signora Jewels.

An approximately 3.00 ct oval brilliant measuring 11.89 × 8.18 × 5.15 mm is secured in a four-prong cathedral basket with a hidden halo and 40 round brilliant accent diamonds totaling approximately 0.20 ct.

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

Each metal color is shown in the photos. Choose your preferred center diamond weight and metal from the options on this page.

The elongated oval brilliant is elevated within a four-prong cathedral basket that allows the center stone to remain the unmistakable focal point. At Signora Jewels, a hidden halo of round diamonds is tucked beneath the center while additional round diamonds are set into the hand-engraved vintage shank. Fine milgrain edges highlight the engraved details without distracting from the oval diamond.

The approximately 2.10 mm comfort-fit shank flows naturally into the cathedral shoulders, creating an elegant profile beneath the center stone. The open gallery allows light to enter beneath the pavilion while the hidden halo introduces sparkle visible only from the side, preserving the clean appearance of the ring when viewed from above.

FAQ

What is a hidden halo?
A hidden halo places accent diamonds beneath the center stone instead of around its outline. This creates sparkle from the side while maintaining a clean top view.

Why is the shank hand engraved?
The engraved pattern and milgrain edging create vintage-inspired detail that enhances the ring without competing with the oval center diamond.

Can this ring be paired with a wedding band?
Yes. The cathedral basket allows many straight wedding bands to sit close, while vintage-inspired bands complement the engraved shank and hidden halo.

Are the green spots in the image emeralds?
No. According to the provided specifications, those green areas are reflections from the lighting. The ring uses only lab grown diamonds for its accent stones.
