The 2N Graded Premium Lab Grown Diamond Identical to Nature’s Own

The same carbon crystal. The same hardness. The same fire and brilliance as a mined stone, identical in every way a gemologist can measure.

What is The 2N Graded Premium Lab Grown Diamond?

Before a stone carries the 2N Graded name, we examine it by hand under the loupe, and if an inclusion is visible to the eye, it is turned away. We then judge its cut and brilliance, and keep only stones with Excellent polish and symmetry, graded Ideal for cut wherever a cut grade applies. Each one is IGI certified and arrives with its report. Only the top 30% pass, and we turn away the other 70%.

IGI Certified Graded by the International Gemological Institute

Your piece is delivered with its IGI report card.

The Story of Onda Azzurra

In 14K White Gold, Onda Azzurra is a necklace, centred on a 0.89 ct cushion-cut lab-grown diamond, with 2.99 ct of diamonds in all. A cushion outline gives the stone a plush presence, while the setting is shaped to flatter the diamond whenever it moves. It layers easily or stands alone; 14K White Gold keeps every line cool and bright. Crafted at our bench in New York, it is a necklace that becomes a habit, built to be worn. It hangs on an 18 in 2.5 mm rope chain in 14K White Gold (5.6 g).
