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.

This round Lab Grown Diamond engagement ring from Signora Jewels places sixteen 1.70 mm diamonds around the center like separate beads of light. The scalloped outline leaves small breaks between the stones, so the 7.40 mm center remains easy to read instead of disappearing inside a solid rim.

Six prongs hold the center above the halo. Another sixteen 1.30 mm rounds run along the shoulders, then stop before the lower shank so the palm side stays smooth against the finger.

The head has real width from above. From the side, the open gallery lets light pass beneath the center and gives a wedding band room to sit close.

The halo does not form a flat circle. Each accent rises as its own scallop, giving the edge a softer rhythm while keeping the center diamond visually separate.

About Lab Grown Diamonds

A round brilliant is cut with 57–58 facets arranged to return light toward the eye. Here, the larger halo diamonds repeat that round pattern around the center without covering its outline.

Lab grown diamonds have the same carbon crystal structure, hardness and optical properties as mined diamonds. They are graded on 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 has more strengthening alloy for daily wear, while 18K has higher gold content and deeper color; compare them in the metal guide.

Order in your known US size. The broad halo carries more visual weight than a plain solitaire, so a close fit helps keep the head centered; check the ring size and fit guide. Clean with warm water, mild soap and a soft brush, then rinse and pat dry.

FAQ

Can I choose another center diamond size?
Yes. The round center is available from 1 to 4.5 ct, and the head and metal weight scale to the selected carat. The photographed configuration uses an approx. 1.50 ct center measuring 7.40 mm.

How many diamonds are in the scalloped halo?
The scalloped halo contains 16 round diamonds measuring approximately 1.70 mm each. Together they weigh approx. 0.320 ct and form the larger outer border around the center.

What is the total accent-diamond weight?
The 32 accent diamonds total approx. 0.480 ct. That figure combines the 0.320 ct halo with 0.160 ct across the pavé shoulders.

How is the center diamond held?
The center diamond is held by six prongs above the halo. Six points of contact spread the hold around the stone while leaving the pavilion open beneath it.

What is the difference between a scalloped halo and a standard halo?
A scalloped halo gives each surrounding diamond its own rounded rise instead of forming one flat circular edge. The spaces between the accents make the border look more dimensional from above.

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

How do lab grown diamonds compare with mined diamonds?
Lab grown diamonds match mined diamonds in carbon structure, hardness and optical behavior; their origin is different. Signora Jewels supplies this ring only with Lab Grown Diamond stones.
