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 marquise lab grown diamond cluster engagement ring from Signora Jewels.

A 1.50 ct, 11.95 × 5.91 mm marquise center sits in an elevated Six-Prong setting, framed by 8 marquise side diamonds totaling approx. 0.53 ct. Approx. 2.03 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 11.95 × 5.91 mm marquise vertically, with six prongs protecting its pointed ends and holding the long outline clear of the shoulders. Eight smaller marquise diamonds branch away from the center in leaf-like clusters, giving this engagement ring its vine pattern without closing the center inside a halo.

The gallery sits approximately 6.5–7.0 mm high. Below it, the shank narrows to about 1.80 mm wide and 1.80 mm thick, while the upper shoulders spread to roughly 4.5–5.5 mm around the marquise clusters.

Every side stone repeats the pointed outline of the center, but at a smaller scale. That repetition pulls the eye outward through the shoulders while the 1.50 ct marquise remains dominant from tip to tip. See the diamond stone guide for more on elongated diamond proportions.

About Lab Grown Diamonds

The marquise center spreads its visual weight along the finger, while the eight smaller marquise diamonds repeat the same pointed geometry through the shoulders. The photographed center measures 11.95 mm from tip to tip, giving the design a pronounced north-to-south profile.

Metal, Care & Fit

White gold and platinum keep the prongs visually close to the diamonds. Yellow and rose gold create stronger contrast around the leaf-shaped clusters and open gallery. Compare the choices in the metal guide. Clean beneath the raised center and between the clustered marquise stones with warm water, mild soap and a soft brush.

FAQ

How are the pointed ends of the center marquise protected?
The center is held in a Six-Prong setting with support at both pointed ends. Those end prongs protect the most exposed parts of the 11.95 mm outline.

How many side diamonds are used in this design?
Eight marquise diamonds form the side clusters and total approximately 0.53 ct. Their pointed outlines repeat the shape of the main marquise rather than introducing another diamond shape.

What makes the shoulders look like leaves?
The eight marquise accents are arranged along sculpted branching metalwork, so each pointed stone reads like a small leaf extending away from the center.

How high does the center sit?
The setting rises approximately 6.5–7.0 mm. That height separates the 1.50 ct center from the surrounding marquise clusters and leaves the gallery open underneath.

Which metal gives the strongest contrast around the side clusters?
Yellow and rose gold make the outlines of the eight marquise accents easier to distinguish from the surrounding metal. White gold and platinum create a brighter, more continuous look.
