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 Bastione Eterno
You bake bread on a rainy morning, flour on your cheek and the whole house smelling of yeast. The loaf rises under its cloth like a small warm moon. Held in 18K Yellow Gold, its oval-cut 2N Graded Premium Lab Grown Diamond glows on your hand as the oven fills the kitchen with amber light.
“In every diamond, a small sun rising for the one who keeps it.”
