Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of an 8 x 4 mm marquise diamond, casting a delicate shadow that dances along the slender yellow gold band. This semi-set solitaire invites you to choose a center stone that echoes your unique story.

Crafted from warm 10K yellow gold, the band is polished to a soft glow, its gentle curve designed for everyday wear. The low-profile setting keeps the diamond close to the hand, balancing elegance with comfort. Each piece is meticulously finished in our Williamsburg studio, ensuring smooth edges and a secure fit.

Our commitment to ethical jewelry shines through the choice of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint.

Ideal for those who appreciate refined simplicity, this solitaire suits slender fingers and pairs effortlessly with stacking bands or wedding rings. Its modest height makes it glove-friendly and unobtrusive for daily life.
