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%.
Your piece is delivered with its IGI report card.

The Story of Alphonse de Marbre
In Platinum, Alphonse de Marbre is a tennis necklace, centred on a 75 ct emerald-cut lab-grown diamond. The Emerald Cut's open table rewards a clear stone; the mounting holds the diamond securely in daylight and lamplight alike. It sits close without weighing on the neck; Platinum adds weight, strength and lasting whiteness with ease. Built to order and finished by hand in New York, meant to be worn often, it is a necklace that feels made for you.
“Soon enough, good fortune is drawn to clear light — let it catch the light.”
