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 brings together graceful proportions and intricate craftsmanship. At the center, a 1.20 ct oval diamond is lifted in a secure four-prong setting, framed by marquise-inspired side details that create a flowing, nature-inspired silhouette.

The side diamonds are arranged in delicate leaf-like clusters, adding sparkle and texture while keeping the center stone as the focal point. Fine milgrain edging enhances the vintage character and gives the ring beautiful detail up close.

Made to order in your choice of center size and metal, this design offers the freedom to create a ring that feels personal while enjoying the beauty and value 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 — the only difference is origin.

Will the side diamonds remain the same?
Yes. The nature-inspired accent design remains part of the ring and is included as shown.

Which metals can I choose?
Silver, 10K / 14K / 18K gold in yellow, white or rose, and Platinum.

Is this ring suitable for everyday wear?
Yes. The oval center is protected by a secure four-prong setting, while the smooth high-polish band is designed for comfortable daily wear.
