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 cushion lab grown diamond halo engagement ring is designed for someone who loves bold sparkle with distinctive detail. At the center sits a cushion-cut diamond framed by a sculpted halo that follows the shape of the stone, creating a larger visual presence and exceptional brilliance.

Along each shoulder, graduated oval and round accent diamonds add extra light and texture. Fine milgrain detailing around the side stones gives the ring a vintage-inspired character while keeping the overall look refined and wearable.

Made to order in your choice of center size and metal, this design lets you create a ring that feels personal from the very beginning. The combination of a cushion center, decorative halo, and diamond-set shoulders creates a memorable engagement ring built for everyday wear.

About Lab Grown Diamonds

A cushion's pillow outline and rounded corners give a softer, warmer glow, with larger facets that scatter light in broad flashes. It pairs naturally with vintage, halo, and double-halo designs and wears gently against the skin.

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.

FAQ

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.

Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds are chemically, physically, and optically identical to mined diamonds and are graded on the same 4C scale.

Will this ring keep its sparkle over time?
Yes. Lab grown diamonds are a 10 on the Mohs hardness scale and are durable enough for everyday wear.

Can I choose a different metal?
Yes. This ring is available in Silver, 9K, 14K, and 18K gold in yellow, white, and rose, plus Platinum.

What makes this design unique?
The sculpted cushion halo and diamond-accented shoulders create a larger visual footprint while preserving the soft shape and brilliance of the cushion center stone.
