Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, graceful shadow across the hand. This semi-set engagement ring invites you to select a center stone that echoes your personal story.

Crafted from warm 14K rose gold, the band is shaped and polished in our Williamsburg studio to a smooth, comfortable fit that wears effortlessly every day. The low-profile prongs cradle the marquise stone securely while allowing light to flood its pointed ends, enhancing the gem’s signature tapered drama.

Each ring reflects our commitment to ethical jewelry: the marquise center is lab-grown, offering clarity and brilliance with a smaller environmental footprint. This choice aligns with a modern approach to sustainability without compromising on sparkle.

Designed for those who appreciate refined geometry and subtle romance, the slender band complements slender fingers and pairs beautifully with stacking rings or a wedding band. Its modest height ensures glove-friendly wear and ease of movement.

Should you need resizing or prefer a custom finish, our Brooklyn studio offers personalized consultations to ensure your ring fits as naturally as it feels.
