Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, confident silhouette across the hand. This three-stone semi-set engagement ring in 14K yellow gold frames a 10 x 5 mm marquise center with two delicate side stones, emphasizing architectural clarity and modern balance.

Crafted in Williamsburg, the band’s smooth finish and low-profile setting ensure a comfortable fit for daily wear, while the secure prong setting highlights the diamond’s dramatic shape without excess metal. Each piece is meticulously inspected to meet exacting standards of polish and symmetry.

Our lab-grown diamonds offer the same optical brilliance as mined stones with a smaller environmental footprint, reflecting a commitment to ethical jewelry without compromise.

The slender marquise shape visually elongates the finger, ideal for those who appreciate refined geometry and a ring that layers effortlessly with other bands. Its semi-set design invites you to select a center stone that resonates personally, making it a versatile foundation for custom design.

Resizing is straightforward, handled in-studio to maintain the ring’s structural integrity and finish.
