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 cut lab grown diamond engagement ring brings together soft curves, brilliant sparkle, and a timeless halo silhouette. A cushion center diamond sits within a frame of round accent diamonds that visually enhance its size and presence.

Additional pavé-set diamonds continue along the shoulders, creating a continuous flow of light from every angle. The elevated gallery allows light beneath the center stone while maintaining an elegant, balanced profile on the hand.

Made to order in your preferred metal and center size, this design combines classic halo styling with the value and beauty of lab grown diamonds.

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.

What does a halo setting do?
A halo surrounds the center diamond with smaller diamonds, increasing overall sparkle and creating the appearance of a larger center stone.

Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds are chemically, physically, and optically identical to mined diamonds and are graded using the same standards.

Which metals can I choose?
Silver, 9K / 14K / 18K gold in yellow, white or rose, and Platinum.

Is this ring made to order?
Yes. Every Signora Jewels ring is crafted to order according to the options you select.
