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.

Halo

An independent IGI grading report is included when the selected individual lab-grown center or primary diamond is 0.50 ct or larger.

What you're seeing: a 3.03 CT radiant lab grown diamond center, set above a 60-stone hidden halo accent arrangement (approx. 0.34 CT) — approx. 3.38 CT total, shown here in yellow gold and white gold.

Make it yours: choose your center diamond (1 ct – 4.5 ct) and your metal — Silver, 9K / 14K / 18K gold in yellow, white or rose, or Platinum. Pricing updates with each choice, and every ring is made to order. Changing the size changes only the center stone; the hidden halo diamonds and design stay the same.

This radiant lab grown diamond hidden halo engagement ring combines bold brilliance with thoughtful detail. The elongated radiant center creates impressive presence, while a delicate hidden halo tucked beneath the gallery adds sparkle visible only as the ring catches the light.

From above, the design reads as a clean and elegant radiant solitaire with a diamond-accented band. Look closer and the hidden halo reveals an additional layer of craftsmanship, framing the center stone with brilliance without overwhelming its shape.

Made to order in your chosen metal and center size, this ring is designed for couples who want a striking center diamond balanced by refined details that reveal themselves over time.

Brilliance Above and Below

The hidden halo sits just beneath the radiant center stone, creating flashes of light from side angles while preserving a clean top-down appearance. Combined with the pavé band and cathedral profile, it delivers layers of sparkle that feel sophisticated rather than flashy.

Why Choose a Radiant Cut Diamond?

A radiant marries an emerald's trimmed-corner outline with brilliant faceting, so it throws lively sparkle while keeping a bold rectangular footprint. The cropped corners are structurally tough and seat securely in prong or halo settings.

About Lab Grown Diamonds

Every Signora Jewels diamond is grown in a controlled lab using the CVD process, producing a stone that is chemically, optically, and physically identical to a mined diamond — same hardness, same fire, graded on the same 4C scale. Because the supply chain is short and traceable, you get a larger, cleaner stone for the same budget and a documented origin, with no mining footprint. The result is a diamond that looks and tests exactly as a natural one, with more carat and clarity for your money.

Available Customizations

Different center stone sizes
Natural or lab grown diamonds
Alternative precious metals

FAQ

What makes this hidden halo different from a traditional halo ring?
The hidden halo sits beneath the center diamond rather than surrounding it from the top view, adding sparkle while preserving the clean appearance of a solitaire.

Are the side diamonds included?
Yes. All accent diamonds in the hidden halo and pavé band are included in every version of the ring.

Will a larger center diamond change the design?
The setting is proportionally adjusted for the chosen center size, but the hidden halo and accent diamond layout remain consistent.

Does the price include the center diamond?
Yes. The listed configuration includes the center lab grown diamond; you can adjust size, stone type, and metal in the customizer and the price updates automatically.

Are lab grown diamonds real diamonds?
Yes. They are identical to mined diamonds in chemistry, hardness, and sparkle, and are graded on the same 4C scale — the only difference is origin.

What metals and colors can I choose?
Sterling Silver, 9KT, 10KT, 14KT, and 18KT Gold, and Platinum — gold is available in yellow, white, and rose.

Can I change the center stone size?
Yes. Center sizes from 1 CT to 4.5 CT are available, and the setting is scaled to suit the stone you choose.

How do I get the right ring size, and can it be resized?
Choose your size in the customizer at checkout; most designs can also be resized — contact us with your details and we'll advise on the specific style.

Is the stated diamond measurement exact?
Measurements are approximate and can vary slightly with each diamond's proportions and cut.
