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 cluster engagement ring from Signora Jewels.

A 1.50 ct, 9.26 × 6.39 mm oval center sits in an elevated Six-Prong setting, with 2 marquise and 2 round side diamonds totaling approx. 0.06 ct. Approx. 1.56 ct total.

Made to order in 11 metals: silver, 10K/14K/18K gold (yellow, white, rose) and platinum.

Each metal color is shown in the photos. Choose your center size and metal in the options on this page.

Signora Jewels sets the 9.26 × 6.39 mm oval vertically above sculpted vine-like shoulders. Six prongs hold the center clear of the surrounding metalwork, while two marquise and two round diamonds sit lower in the open engagement ring shoulders. The stones read like small leaves and buds rather than a straight row of side diamonds.

The center rises approximately 6.5–7.0 mm, leaving an open gallery underneath. At the bottom, the shank is about 2.00 mm wide and 1.70 mm thick, then expands through the shoulder area to roughly 5.5–6.5 mm where the vine work branches around the accent stones.

2 marquise side diamonds, approx. 0.03 ct total
2 round accent diamonds, approx. 0.03 ct total
Six-Prong elevated center with open gallery
Sculpted nature-inspired Cluster shoulders

The side stones are deliberately sparse. One marquise and one round sit within the vine work on each side, giving the shoulders flashes of light without turning them into pavé. That leaves the elongated oval as the clear focal point while the open metalwork carries the floral character around it.

About Lab Grown Diamonds

The oval center spreads its 9.26 mm length along the finger, while the smaller marquise and round stones break up the shoulder line with shorter flashes of light. See the diamond stone guide for more on oval proportions, cut and grading.

Metal, Care & Fit

White gold and platinum keep the prongs and side-stone settings visually close to the diamonds. Yellow and rose gold make the vine structure and open spaces easier to read. Compare the choices in the metal guide. Clean beneath the raised center and around the four shoulder diamonds with warm water, mild soap and a soft brush.

FAQ

How many side diamonds are in this ring?
There are four side diamonds: two marquise and two round. Together they total approximately 0.06 ct and sit within the vine-style shoulders.

Why is the oval center raised above the shoulders?
The setting height is approximately 6.5–7.0 mm, which keeps the 9.26 × 6.39 mm oval clearly above the side clusters. The open gallery also leaves access beneath the stone for cleaning.

What do the marquise diamonds add to the design?
The two marquise diamonds follow the leaf shapes in the sculpted shoulders. Their pointed outlines reinforce the nature-inspired pattern without forming a continuous row of stones.

Will a straight wedding band sit completely flush?
The open shoulder clusters occupy space beside the raised center, so a straight band can leave a small gap. A contoured band follows the ring's organic side profile more closely.

Which metal makes the vine design easiest to see?
Yellow and rose gold create stronger contrast around the four side diamonds and open metalwork. White gold and platinum make the setting read more continuously with the stones.
