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 marquise lab grown diamond engagement ring combines an elongated center stone with a softly tapering pavé band, creating a design that feels graceful on the hand while maximizing visual presence. The pointed silhouette naturally draws the eye along the finger, giving the center diamond an elegant, lengthening effect.

Thirty-four accent diamonds are set into the shoulders of the ring, adding a ribbon of sparkle that leads toward the center stone without overwhelming it. The four-prong setting keeps the profile open so light can reach the diamond from multiple angles.

Made to order in your chosen center size and precious metal, this design is crafted for couples who want the timeless look of a solitaire with the added brilliance of pavé detailing.

About Lab Grown Diamonds

A marquise stretches weight across a long, pointed boat shape, so it presents one of the largest face-up sizes per carat. Its tapering ends draw the eye down the finger and make a confident, regal statement.

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 marquise diamond look larger than other shapes?
Yes. The elongated marquise shape typically shows a larger face-up appearance than many other shapes of the same carat weight.

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 ring is crafted to your selected center size and metal choice before shipping.
