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 is designed around graceful proportions and everyday wear. A beautifully elongated oval center rises above a slim solitaire band, creating a clean profile that keeps the focus on the diamond.

From the side, a hidden halo of twelve lab grown diamonds adds an unexpected flash of brilliance beneath the center stone. It stays invisible from most top-down angles, preserving the simplicity of a classic solitaire while rewarding a closer look.

Made to order in your choice of center size and metal, this ring lets you create a look that feels personal from the very beginning. The open basket allows light to reach the diamond from multiple angles, enhancing sparkle throughout the day.

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. Lab grown diamonds are chemically, physically, and optically identical to mined diamonds and are graded using the same 4C standards.

Will a lab grown diamond last a lifetime?
Yes. Lab grown diamonds rank 10 on the Mohs hardness scale and are durable enough for everyday wear.

What does the hidden halo add?
The hidden halo places 12 accent diamonds beneath the center stone, adding sparkle from side angles while maintaining a classic solitaire appearance from above.

Which metals can I choose?
Silver, 9K / 14K / 18K gold in yellow, white, or rose, and Platinum.
