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.
Bench made in New York by our Master Artisans, with new gold only, never melted down or recast. Delivered in 10–14 days.

The Story of Promontorio Profondo
You walk the High Line at dusk in late spring, wild grasses brushing your hand. The city hums below like a distant sea and the air smells of rain on warm stone. The necklace in 18K White Gold rests cool against your skin as the rooftops begin to light up one by one.
“A brilliant beginning always remembers its way back to you.”
