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 marquise lab grown diamond engagement ring should feel distinctive from every angle, and this split shank design does exactly that. The elongated marquise center rises above two diamond-set bands that cross beneath the stone, creating movement, light, and a graceful profile on the hand.

The pointed marquise silhouette naturally elongates the finger while the pavé-set accent diamonds add brilliance across both sides of the split shank. The result is a ring that feels elegant and modern without losing the romance expected of a proposal piece.

Made to order in your choice of center size and metal, this design gives you the freedom to create a ring that matches your story while enjoying the beauty, value, and responsible origin of a lab grown diamond.

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 shape gives a larger face-up appearance than many other cuts 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. Each ring is crafted specifically for your selected center size and metal combination.
