Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its pointed ends drawing the eye along a sleek, confident line. This semi-set engagement ring invites you to choose a 6 x 3.5 mm center stone that balances architectural drama with refined minimalism.

Crafted in 14K white gold, the mounting features delicate accent stones that enhance the diamond’s clarity without overpowering its shape. The band’s low-profile setting ensures a comfortable fit beneath gloves or daily wear, while the polished finish reflects the Brooklyn studio’s meticulous handwork.

Each lab-grown diamond offers the brilliance and purity of mined stones with a smaller environmental footprint, aligning with a modern ethical sensibility.

Designed for those who appreciate structured elegance, this ring complements slender fingers and pairs effortlessly with stackable bands. Its streamlined form suits a lifestyle that values both subtlety and statement.
