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.

Signora Jewels sets the 10.00 × 8.00 mm oval above a band worked with far more detail than a conventional diamond shoulder. Six substantial prongs hold the 2.42 ct reference center, while milgrain-edged loops cross along the band around marquise and round accent diamonds.

Seven 4.00 × 2.00 mm marquise diamonds total approximately 0.37 ct. Another 56 rounds in 1.00, 1.10 and 1.50 mm sizes add 0.456 ct. Together the accents contribute 0.826 ct, bringing the reference ring to approximately 3.246 ct total diamond weight.

About Lab Grown Diamonds

The 2.42 ct reference oval is accompanied by 63 smaller diamonds. Seven marquise accents contribute approximately 0.37 ct, while 56 rounds contribute 0.456 ct. Main and side diamonds together bring the CAD reference design to approximately 3.246 ct total diamond weight.

Metal, Care & Fit

The CAD gives an 18K metal weight of 6.50 g. The milgrain loops, recessed engraving and 63 accent settings create more small surfaces than a plain band, so clean from both sides with warm water, mild soap and a soft brush. Work gently behind the marquise diamonds and through the crossings in the shoulder pattern.

FAQ

How much total diamond weight is in the 2.42 ct reference ring?
The reference design totals approximately 3.246 ct. It combines a 2.42 ct oval center with 0.826 ct of marquise and round side diamonds.

How many accent diamonds are worked into the vintage band?
There are 63 accent diamonds: seven marquise cuts and 56 rounds. The marquise stones total approximately 0.37 ct and the rounds total 0.456 ct.

What makes the shoulders different from a standard pavé band?
The diamonds sit inside looping, milgrain-edged metalwork rather than one straight pavé channel. Marquise cuts fill the pointed openings while smaller rounds occupy the crossings and surrounding details.

How high does the oval center sit?
The CAD shows an approximately 8.20 mm setting height. The six-prong head rises above the detailed shoulders, leaving the 10.00 × 8.00 mm oval visually distinct from the band.

How should the detailed shoulders be cleaned?
Use warm water, mild soap and a soft brush from both the top and underside. Pay attention to the milgrain edges, engraved recesses and areas behind the 63 smaller diamonds where residue can collect.
