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.

A cushion lab grown diamond engagement ring brings together soft curves, bright sparkle, and a balanced silhouette that feels both modern and enduring. At the center of this design sits a substantial cushion-cut diamond, elevated above a delicate pavé band that adds light without competing with the main stone.

The four-prong setting keeps the profile open so light can enter the diamond from multiple angles, while the pavé-set accent diamonds trace the shoulders with continuous brilliance. From a distance, the ring reads as a classic solitaire; up close, the fine details reveal layers of sparkle.

Made to order and crafted around the center size you select, this ring is designed to celebrate your story with a combination of scale, fire, and everyday wearability.

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. They are chemically, physically, and optically identical to mined diamonds and are graded using the same standards.

Will a lab grown diamond keep its sparkle?
Yes. Lab grown diamonds rank 10 on the Mohs hardness scale and will maintain their brilliance for generations with normal care.

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

Are the side diamonds included?
Yes. The pavé accent diamonds shown are included as part of the ring design.
