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 three-stone engagement ring from Signora Jewels.

The reference ring features an 8.10 × 6.00 mm oval brilliant center diamond of approximately 1.13 ct, paired with two pear brilliant side diamonds totaling approximately 0.50 ct. Approximate total diamond weight is 1.63 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. Choose your preferred metal and center diamond weight using the options above.

The oval center sits between two pear diamonds that taper naturally into the band, creating a balanced profile without making the ring feel wide. Signora Jewels builds each ring around your selected center size so the proportions stay consistent across every option.

A four-prong trellis basket lifts each diamond above an open gallery, allowing light to reach the stones from below. The plain cathedral shank keeps the focus on the three-diamond arrangement while providing a clean profile that pairs easily with a wedding band.

The pear side diamonds point outward from the center, extending the silhouette without overwhelming it. Their shape naturally draws the eye back toward the oval center stone, giving the ring a balanced appearance from every angle.

About Lab Grown Diamonds

Oval lab grown diamonds combine bright brilliance with an elongated outline, while pear side stones frame the center without competing for attention. Every center diamond is F color, VS1 clarity and , providing consistent quality across every available size.

Metal, Care & Fit

Available in silver, platinum and 9K, 14K and 18K yellow, white and rose gold. Clean the ring regularly with warm water, mild soap and a soft brush, paying attention to the spaces beneath the trellis basket where everyday residue can collect.

FAQ

Why are pear side diamonds used in this design?
The pear diamonds taper away from the center stone, creating a balanced three-stone layout that complements the oval shape.

Does the trellis basket affect the appearance?
Yes. The trellis setting raises each diamond slightly and allows more light beneath the stones while keeping the gallery open.

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

Will a wedding band sit beside this ring?
The cathedral shank pairs well with many straight wedding bands, although the exact fit depends on the band profile you select.
