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 vivid yellow radiant-cut lab grown diamond three-stone engagement ring from Signora Jewels.

One 2.01 ct radiant center measuring approximately 7.42 × 6.08 × 4.45 mm, accompanied by two tapered baguette lab grown diamonds totaling 0.32 ct.

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

Approximately 2.33 ct total diamond weight, with three diamonds, a four-prong center and polished tapered shoulders.

Signora Jewels sets a vivid yellow radiant-cut diamond between two tapered baguettes, using the contrast in both color and facet pattern to define this engagement ring. The center measures approximately 7.42 × 6.08 mm and is secured by four rounded corner prongs.

The baguettes sit horizontally beside the center, their wider ends meeting the radiant and their narrower ends pointing toward the band. Each weighs approximately 0.16 ct, giving the ring 0.32 ct of side diamonds and a total of 2.33 ct.

Design highlights

2.01 ct vivid yellow radiant-cut lab grown diamond center
Center dimensions approximately 7.42 × 6.08 × 4.45 mm
Two tapered baguette lab grown diamonds, approximately 0.16 ct each
Four rounded center prongs with stepped side-stone settings
Plain polished shank with shoulders widening near the baguettes
2.33 ct total diamond weight across three stones

The side diamonds introduce long, straight step-cut reflections beside the radiant's smaller facets. The polished shank narrows to approximately 2.10 mm at its base, leaving the three-stone arrangement as the main feature.

FAQ

What makes the center diamond different from the two side diamonds?
The center is a 2.01 ct vivid yellow radiant cut, while the side diamonds are two tapered baguettes totaling 0.32 ct. Their contrasting color and facet patterns create the three-stone design.

How are the tapered baguette diamonds positioned?
Each baguette sits horizontally beside the radiant center, with its wider end facing inward and its narrower end pointing toward the shank. This creates a gradual transition from the broad center to the band.

How is the radiant-cut center secured?
Four rounded prongs hold the radiant center near its corners. The baguettes have separate metal supports at their ends, so all three stones are individually secured.

Will a straight wedding band sit flush beside this three-stone ring?
The side-stone shoulders widen to approximately 3.2–3.8 mm near the center, while the setting height is approximately 6.5–7.0 mm. These measurements do not establish flush clearance, so compare the finished ring with the intended band.

How should I clean around the tapered baguette settings?
Use warm water, mild soap and a soft brush around the four center prongs and the baguette end supports. Rinse thoroughly and pat dry without pulling fabric beneath the side-stone settings.
