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 radiant lab grown diamond cluster engagement ring from Signora Jewels.

A 2.00 ct, 8.64 × 6.30 mm radiant center sits in an elevated Six-Prong setting, with 2 marquise and 4 round accents totaling approx. 0.10 ct. Approx. 2.10 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 8.64 × 6.30 mm radiant vertically above sculpted vine-and-leaf shoulders. Six prongs hold the rectangular center clear of the side metalwork, while two marquise and four round diamonds sit lower within the open engagement ring shoulders.

The setting rises approximately 6.5–7.0 mm, leaving an open gallery beneath the center. At the base, the shank is about 1.80 mm wide and 1.60 mm thick, then opens through the shoulder area to roughly 5.5–6.5 mm where the leaf forms and accent stones spread outward.

Design highlights

2.00 ct radiant center, approx. 8.64 × 6.30 mm in the photos
Center customizable from 1 ct to 4.5 ct
2 marquise side diamonds totaling approx. 0.06 ct
4 round accents totaling approx. 0.04 ct
Six-Prong elevated center with open gallery
Sculpted vine-and-leaf Cluster shoulders

The side stones follow the vines rather than sitting in a straight row. The marquise diamonds echo the leaf shapes, while the smaller rounds fill points of light between them. That keeps the radiant center dominant and lets the open metalwork stay visible from the front and side.

About Lab Grown Diamonds

The radiant cut combines a rectangular outline with a brilliant-style facet pattern, so the 8.64 × 6.30 mm center throws smaller flashes across a broad face. Read more about cut, proportions and grading in the diamond stone guide.

Metal, Care & Fit

White gold and platinum keep the prongs visually close to the center and accents. Yellow and rose gold make the vine structure easier to read around the stones. Compare the choices in the metal guide. Clean beneath the open gallery and around the six side diamonds with warm water, mild soap and a soft brush.

FAQ

How many side diamonds are in this ring?
There are six side diamonds: two marquise and four round. Together they total approximately 0.10 ct around the 2.00 ct photographed center.

What do the marquise diamonds do visually?
The two marquise diamonds follow the leaf forms in the sculpted shoulders. Their pointed outlines carry the nature-inspired pattern away from the rectangular radiant center.

How high does the radiant center sit?
The setting height is approximately 6.5–7.0 mm. The open gallery keeps the 8.64 × 6.30 mm center above the vine shoulders and leaves access beneath it for cleaning.

Will a straight wedding band sit completely flush?
The sculpted shoulder work occupies space beside the raised center, so a straight band can leave a small gap. A contoured band follows the organic profile more closely.

Which metal makes the leaf detail easiest to see?
Yellow and rose gold create stronger contrast around the marquise and round accents. White gold and platinum make the prongs and diamonds read as a brighter continuous surface.
