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.

At a glance

An oval Lab Grown Diamond scalloped double-halo engagement ring from Signora Jewels.

As shown, the ring carries a 5.000 ct oval center measuring Approx. 13.00 × 10.00 mm, surrounded by 72 round halo diamonds totaling Approx. 1.080 ct.

Seventy-three diamonds total Approx. 6.080 ct in a four-prong center setting with two raised, individually set halo rows.

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

Made to order — the price updates with your selected center size and metal. Adjust the oval proportions, halo spacing or basket height through our custom jewelry service.

Signora Jewels sets the 13.00 × 10.00 mm oval above two separate rows of round diamonds. The inner row closes the space around the center, while the larger outer row forms a scalloped edge that remains visible from every angle.

Four prongs hold the oval without running metal along its long sides. The raised gallery leaves room beneath the pavilion for cleaning, and the plain lower shank keeps the palm side free of exposed diamond settings.

The two halo rows do not read as one flat border. Their different stone sizes create a tighter inner line and a broader outer flash, extending the oval outline across the finger without changing its elongated shape.

The outer halo controls the face-up spread. Its larger rounds push beyond the inner border, while the smaller diamonds beside the oval keep the center outline clean instead of filling the space with heavy metal.

About Lab Grown Diamonds

An oval brilliant carries round-style faceting through an elongated outline. The smaller halo diamonds repeat that light pattern at two scales, creating a tight inner flash and a wider scalloped border.

Lab grown diamonds have the same carbon crystal structure, hardness and optical properties as mined diamonds. Compare cuts, proportions and grading in the diamond and stone guide.

Metal, Care & Fit

Choose silver, 9K/14K/18K gold in yellow, white or rose, or platinum. 9K contains more strengthening alloy, while 18K contains more gold and carries richer color; compare the choices in the metal guide.

Order in your known US size. The broad double halo needs a secure fit to keep the oval upright. Clean beneath the center and between both halo rows with warm water, mild soap and a soft brush, then rinse and pat dry.

FAQ

Can I choose another center diamond size?
Yes. The oval center is available from 1 to 5 ct, and the basket, halo proportions and metal weight scale with the selected carat. The photographed configuration uses an Approx. 5.000 ct center measuring 13.00 × 10.00 mm.

What is the total diamond weight?
The photographed configuration totals Approx. 6.080 ct across 73 diamonds. That includes the 5.000 ct oval center and 72 halo diamonds totaling Approx. 1.080 ct.

How are the halo diamonds arranged?
The setting uses two graduated halo rows around the oval. Twenty-four 1.50 mm diamonds and twenty-four 1.00 mm accents form the inner structure, while twenty-four 1.80 mm rounds create the scalloped outer edge.

How is the oval center held?
The oval center is secured by four prongs placed around its curved outline. The open long sides leave the elongated shape visible and allow light to enter beneath the stone.

Will a wedding band sit beside this ring?
A straight wedding band reaches the plain lower shank but can leave a narrow gap beside the raised double-halo gallery. A gently contoured band follows the lower edge more closely.

How does a double halo compare with a single halo?
A double halo uses two surrounding diamond rows, while a single halo uses one. This design creates a tighter inner border and a wider scalloped outer outline.

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 carries richer color. Both are solid gold choices for engagement-ring wear.

Are the center and halo diamonds included?
Yes. Signora Jewels includes the selected oval center and all 72 round halo diamonds in the completed ring.
