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 oval lab grown diamond engagement ring combines graceful proportions with eye-catching brilliance. At the center sits an oval diamond framed by a sparkling halo, creating a larger visual presence while drawing light from every angle.

The split shank design adds dimension and balance to the ring, with pavé-set diamonds flowing along both sides of the band and around the halo. The result is a ring that feels bright and luxurious without overwhelming the center stone.

Made to order in your chosen metal and center size, this design lets you create a ring that reflects your story while enjoying the value, beauty, and ethical benefits of a lab grown diamond.

About Lab Grown Diamonds

An oval delivers the fire of a round brilliant in a stretched outline that flatters and lengthens the finger. Its longer surface reads larger than a round of the same weight, and the absence of sharp corners means there's no point to chip.

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 identical to mined diamonds in chemistry, hardness, and sparkle, and are graded on the same 4C scale.

Will a halo make the center diamond look larger?
Yes. The surrounding halo of diamonds increases the visual footprint of the center stone and adds additional sparkle.

Can I choose a different metal?
Yes. Choose from silver, 9K, 14K, or 18K gold in yellow, white, or rose, plus platinum.
