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 engagement ring brings together bold center-stone presence and graceful detail. A softly rounded cushion diamond sits above an elegant split shank, creating an open profile that draws the eye directly toward the center stone.

Thirty-two hand-set lab grown diamonds trace both sides of the split band, adding sparkle from every angle while keeping the cushion center as the focal point. The result is a design that feels substantial, balanced, and full of light.

Made to order in your chosen metal and center size, this ring offers the freedom to create a look that reflects your story while enjoying the value, beauty, and traceable origin of a lab grown diamond.

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 pavé 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 a lab grown diamond last?
Yes. Lab grown diamonds have the same hardness and durability as mined diamonds, scoring 10 on the Mohs scale.

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