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 green oval lab grown diamond cathedral engagement ring from Signora Jewels.

A 2.00 ct, 10.19 × 7.14 mm green oval center sits in a Four-Prong setting above engraved cathedral shoulders. No side diamonds. Approx. 2.00 ct total.

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

Choose your center weight and metal for this made-to-order ring.

Signora Jewels keeps the diamond work focused on a single 10.19 × 7.14 mm green oval. Four prongs hold the center above rising cathedral shoulders, while the band itself carries the detail: engraved leaves, small floral forms and fine milgrain edging run along the upper shank.

The lower band is approximately 2.80 mm wide and 1.90 mm thick, giving this ring more metal through the base than the finer vine designs. The center sits about 6.5–7.0 mm high, with open space beneath the oval rather than a diamond-set halo or side cluster.

Design highlights

The engraving is what gives this ring its vintage character. Instead of adding more stones, the shoulders carry carved leaves and scrolls inside a fine beaded border, leaving the green oval completely dominant from the top view.

About Lab Grown Diamonds

The photographed oval measures 10.19 × 7.14 mm, giving the green center a broad face with noticeable length along the finger. With no side diamonds beside it, the oval's outline and color stay uninterrupted. See the diamond stone guide for more on oval proportions and grading.

Metal, Care & Fit

Yellow and rose gold add warmth around the green center and make the engraved leaves easier to read; white gold and platinum create stronger contrast between the colored diamond and the band. Compare options in the metal guide. Use warm water, mild soap and a soft brush around the prongs and inside the engraved recesses.

FAQ

Does this ring have any side diamonds?
No. The green oval center is the only diamond in this design; the shoulder detail comes from engraved metalwork and milgrain rather than additional stones.

How is the oval center held?
The 10.19 × 7.14 mm reference center is secured by four prongs. The cathedral shoulders rise toward the setting without covering the oval's face-up outline.

What makes the band look vintage?
The upper shank carries engraved flower-and-leaf work bordered by fine milgrain. Those details create texture in the metal without adding pavé or side diamonds.

How high does the center sit?
The setting height is approximately 6.5–7.0 mm. That elevation separates the oval from the engraved shoulders and leaves open space beneath the center.

Which metal gives the strongest contrast with the green center?
White gold and platinum create the clearest tonal contrast around the green oval. Yellow and rose gold make the engraved floral pattern more pronounced against the center.
