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 pavé split-shank engagement ring from Signora Jewels.

As shown: a 2.12 ct, 8.90 × 6.40 mm radiant center in a four-prong setting, with 48 round pavé accents totaling approx. 0.288 ct.

Forty-nine Lab Grown Diamond stones total approx. 2.408 ct in the photographed configuration.

Made to order in silver, 9K/14K/18K yellow, white or rose gold, and platinum.

Made to order — the price updates with your selection. Change the center proportion, shoulder spacing or pavé layout through our custom jewelry service.

Signora Jewels sets the 8.90 × 6.40 mm radiant above two diamond-lined arms on each shoulder. The split opens near the center, then closes into one polished lower shank, giving the ring width where it meets the stone without carrying that bulk around the finger.

Forty-eight 1.10 mm rounds sit in U-cut settings along the four upper rails. The openings between the rails let light pass through the shoulders, while four corner prongs leave the radiant’s clipped outline clear.

From above, the split frames the center. From the side, the raised basket leaves room beneath the diamond and gives a wedding band space to sit close.

The split shoulders are the defining detail. They create four narrow lines of light near the radiant, then merge into a single band before reaching the palm.

About Lab Grown Diamonds

A radiant cut combines a trimmed-corner rectangular outline with brilliant faceting, giving it sharper edges than an oval and more scintillation than a step cut. The four corner prongs protect the clipped corners while keeping the long sides visible.

Lab grown diamonds have the same carbon crystal structure, hardness and optical properties as mined diamonds. They are graded using the same cut, color, clarity and carat standards.

Metal, Care & Fit

Choose silver, 9K/14K/18K gold in yellow, white or rose, or platinum. 9K contains more strengthening alloy for daily wear, while 18K has higher gold content and richer color; compare them in the metal guide.

Order in your known US size. The upper shank spreads across more of the finger than a plain solitaire, so accurate sizing helps keep the radiant upright; use the ring size and fit guide. Clean between the split rails with warm water, mild soap and a soft brush.

FAQ

Can I choose another center diamond size?
Yes. The radiant center is available from 1 to 4.5 ct, and the basket and metal weight scale to the selected carat. The photographed configuration uses an approx. 2.12 ct center measuring 8.90 × 6.40 mm.

How many pavé diamonds are set into the ring?
The split shoulders contain 48 round pavé diamonds totaling approximately 0.288 ct. Each accent measures approximately 1.10 mm and sits in a U-cut setting.

How is the radiant center held?
The radiant center is secured by four prongs placed at its clipped corners. This protects the corners while leaving the long sides open and visible.

What does the split shank do?
The upper band divides into four pavé-set rails around the center, then merges into one lower shank. This gives the ring more width near the diamond while keeping the palm side smooth.

Will a wedding band sit beside this ring?
A straight wedding band sits close beneath the raised center basket. A small gap can remain beside the split shoulders, while a gently contoured band follows the setting most closely.

What is the difference between 9K and 18K gold?
9K gold contains more strengthening alloy and has a harder surface, while 18K contains more gold and has richer color. Both are solid gold choices for daily engagement-ring wear.

How does a radiant cut compare with an emerald cut?
A radiant cut uses brilliant faceting for tighter sparkle, while an emerald cut uses long step facets for broader flashes. Signora Jewels uses a radiant center in this ring, giving the rectangular outline a livelier light pattern.
