Round Lab Grown Diamond Vine Side-Stone Engagement Ring

Yes. Lab-grown diamonds pass standard thermal and electrical diamond testers because they are pure crystallized carbon — the same material as mined diamonds. Only advanced laboratory spectroscopy can determine origin. Every Signora Jewels lab-grown diamond ships with an IGI report, and its number is laser-inscribed on the girdle so you can verify the stone free at igi.org.

Yes. Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds, and the FTC recognizes them as real diamonds — unlike simulants such as cubic zirconia. They are graded on the same 4Cs of cut, color, clarity, and carat. Signora Jewels uses IGI-certified lab-grown diamonds in every made-to-order diamond ring.

No. Lab-grown diamonds never cloud, fade, or yellow — at Mohs 10 hardness they are structurally identical to mined diamonds, so the brilliance is permanent. Any dullness is a surface film of skin oil or soap, which washes off with warm soapy water and a soft brush. Your Signora ring will sparkle the same decades from now.

Use the Signora Jewels ring size guide — the on-page “Find my size” tool converts a simple millimeter measurement of your finger or an existing ring into your US size. Measure in the evening when fingers are largest, and go up half a size if you’re between sizes or choosing a wide band. Every ring is made to order in your exact size.
