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

A green marquise cut lab grown diamond vintage engagement ring from Signora Jewels.

A 9.8 × 5.5 mm Dutch marquise center weighing approx. 1.00 ct, held by protective end prongs and side claws. Approx. 16–20 small round brilliant accents total 0.04 ct, bringing the combined diamond weight to 1.04 ct.

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

Choose your metal and color from the options on this page. The center diamond is fixed at approximately 1.00 ct.

The green diamond has two sharply pointed ends, and both sit beneath shaped metal prongs. Signora Jewels sets this 9.8 × 5.5 mm Dutch marquise lengthwise along the finger, leaving its wide middle visible between four additional side claws. The center weighs approximately 1.00 ct and sits above a raised open gallery.

Instead of plain shoulders, the band is worked with small flowers, curling stems and leaf shapes. Fine beaded edges run above and below the engraving. The CAD also accounts for approximately 16–20 tiny round diamonds weighing just 0.04 ct together; the decorative metalwork remains the dominant detail along the shank.

About Lab Grown Diamonds

The green center is a lab grown diamond cut in the Dutch marquise shape, with two pointed ends and an elongated faceted outline. Its green color contrasts with the light-colored metal in the reference image and the smaller white diamond accents. Learn more about diamond proportions in our diamond and stone guide.

Metal, Care & Fit

Choose silver, 10K, 14K or 18K yellow, white or rose gold, or platinum. The pointed-end prongs protect the narrow tips, but the raised center still needs care around fitted sleeves. Clean the engraved floral sections with warm water, mild soap and a soft brush, following the small curves between petals and the milgrain borders. Remove the ring before heavy lifting or activities that place pressure on the center setting.

FAQ

Is the green center a lab grown diamond?
Yes. The green Dutch marquise center is a lab grown diamond weighing approximately 1.00 ct. It is not a separate colored gemstone.

How are the two pointed ends protected?
Shaped metal prongs cover both narrow ends of the marquise diamond, while additional side claws secure the stone along its edges. The center remains open between the prongs.

Are the flowers on the shoulders made from diamonds?
No. The larger flowers, leaves and curling stems are sculpted metalwork. The CAD separately specifies approximately 16–20 tiny round brilliant accents totaling 0.04 ct.

Does this ring have a halo?
No. The green marquise center sits in a raised prong basket without a surrounding halo. The ornamental detail is concentrated along the shoulders.

How should I clean the milgrain and floral engraving?
Use warm water, mild soap and a soft brush, working gently between the flower petals and along the fine beaded borders. Dry the small recessed areas carefully with a lint-free cloth.
