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.

A marquise cut lab grown diamond vintage engagement ring with leaf-and-vine shoulders from Signora Jewels.

A 15.0 × 7.4 mm marquise center weighing approx. 3.00 ct, held by protective pointed-end prongs and side claws. Approx. 12–16 round brilliant accents total 0.06 ct, bringing the combined weight to 3.06 ct.

The gold leaves reach up around this marquise instead of stopping at the shoulders. Signora Jewels sets a 15.0 × 7.4 mm center diamond between protective pointed-end prongs, with sculpted leaf tips following the stone's long edges. The 3.00 ct reference center fills the middle of the ring, while the branching metalwork climbs partway around its setting.

Along both shoulders, small round brilliant diamonds sit between curling gold stems and cutout leaves. The CAD estimates 12–16 accents totaling 0.06 ct. The open spaces remain visible around the stones, and the decorated shoulders taper into a 1.60 mm polished lower shank.

About Lab Grown Diamonds

The marquise center has two pointed ends and a long faceted outline, with its widest section across the middle. Smaller round brilliant diamonds introduce pinpoints of reflected light among the sculpted leaves without creating a halo around the center. All diamonds are lab grown and selected to F color and VS1 clarity specifications. Read our diamond and stone guide for more about marquise proportions.

Metal, Care & Fit

Choose silver, 10K, 14K or 18K yellow, white or rose gold, or platinum. The raised marquise and projecting leaf shapes require care around fitted sleeves and gloves. Clean with warm water, mild soap and a soft brush, gently reaching through the vine openings and around the small diamonds. Remove the ring before heavy lifting or activities that place pressure on the pointed-end prongs.

FAQ

Are both marquise points protected?
Yes. Shaped metal prongs cover both pointed ends of the center, while additional side claws secure the wider edges. The leaf detailing sits around the protected setting.

Do the gold leaves cover the diamond?
The sculpted leaves rise beside portions of the marquise but leave its central faceted surface exposed. The botanical detailing frames the stone without forming a complete bezel.

Where are the smaller diamonds set?
Approximately 12–16 round brilliant diamonds are placed within the leafy shoulder motifs. They weigh 0.06 ct together and do not form a surrounding halo.

Can I choose a different center diamond size?
Yes. The marquise center is customizable from 1 ct through 4.5 ct, including the reference 3.00 ct. The basket is made to suit the chosen center dimensions.

How should I clean the detailed leaf shoulders?
Use mild soap, warm water and a soft brush, carefully moving between the carved leaves, curling stems and small round diamonds. Rinse thoroughly and dry the openwork with a lint-free cloth.
