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 round lab grown diamond halo engagement ring from Signora Jewels.

A 0.85 ct, 6.00 mm round brilliant sits in a Four-Prong setting with round halo and shoulder diamonds totaling approx. 0.51 ct. Approx. 1.36 ct total.

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

Choose your metal in the options on this page.

Signora Jewels sets the 6.00 mm round brilliant inside two diamond-set curves that twist around the center rather than forming a flat circular border. The pavé continues into the divided shoulders, giving this halo engagement ring movement from the center all the way into the upper shank.

The Four-Prong center sits approximately 6.0–6.5 mm high. A 2.00 mm lower band gives the ring substance at the base, while the upper shoulders broaden to roughly 3.8–4.5 mm around the twisting diamond work.

Design highlights

0.85 ct round brilliant center · approx. 6.00 mm diameter
Round halo diamonds totaling approx. 0.20 ct
Round pavé shoulder diamonds totaling approx. 0.31 ct
Four-Prong center setting
Twisted Halo with Split Shank pavé shoulders
Approx. 1.36 ct total diamond weight

The crossing curves are the part you notice after the center. One line sweeps past the other around the halo, then both continue into the pavé shoulders, so the diamond work reads as a continuous twist rather than separate halo and band sections.

About Lab Grown Diamonds

The round brilliant center uses a symmetrical facet pattern built for strong light return, while the smaller rounds add tighter flashes around the halo and shoulders. Read more in the diamond stone guide.

Metal, Care & Fit

White gold and platinum keep the twisted pavé visually close to the diamonds; yellow and rose gold create stronger contrast between the crossing curves. Compare choices in the metal guide. Clean beneath the center and between the pavé twists with warm water, mild soap and a soft brush.

FAQ

What makes the halo look twisted on this ring?
The halo is built from crossing diamond-set curves rather than one flat circular border. Those curves continue into the divided shoulders, creating the spiral effect visible around the round center.

How much diamond weight is in the halo?
The round halo diamonds total approximately 0.20 ct. They frame the 6.00 mm center while leaving the Four-Prong setting clearly visible.

How much diamond weight is set into the shoulders?
The round pavé shoulder diamonds total approximately 0.31 ct. Combined with the halo, the complete accent setting weighs approximately 0.51 ct.

How high does the center sit?
The setting rises approximately 6.0–6.5 mm. That height keeps the round center clear of the twisting shoulder structure without creating an unusually tall profile.

How should the twisted pavé sections be cleaned?
Use a soft brush between the crossing curves and underneath the center basket. Those narrow spaces collect more residue than the polished lower shank.
