Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a marquise diamond catching light with every movement, its pointed ends lending a refined silhouette to the hand. This semi-set halo engagement ring foundation is crafted in 18K white gold, designed to cradle a 12 x 6 mm marquise stone with precision and grace.

The halo setting enhances the center’s dramatic shape while maintaining a low profile, ideal for daily wear without catching on fabric or gloves. The band’s smooth finish and balanced weight ensure comfort throughout the day, reflecting careful hand-finishing and rigorous inspection in our Williamsburg studio.

Each ring embraces the clarity and sustainability of lab-grown diamonds, offering an ethical alternative without compromise on brilliance or character.

Its streamlined design suits those who appreciate architectural elegance paired with practical wearability, especially flattering on slender fingers or when stacked with complementary bands.
