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 Duc Nocturne

In Platinum, Duc Nocturne is a tennis necklace, centred on a 20 ct Baguette-cut lab-grown diamond. The Baguette is precise, slim and understated, while the tennis design is an unbroken line of light at every turn. It moves softly when worn, and Platinum adds weight, strength and lasting whiteness every time. Hand finished to order at our New York bench, meant to be worn often, it is a necklace to reach for again and again.
