Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, confident sparkle that feels both bold and refined. This semi-set engagement ring in 14K rose gold offers a modern-minimalist frame, where clean lines and subtle accent stones emphasize clarity and architectural grace.

Handcrafted in Williamsburg, the band’s gentle curve and low-profile setting ensure a comfortable fit for daily wear, while the rose gold’s warm glow complements the marquise’s tapered drama. Each piece is meticulously finished and inspected to meet exacting standards of craftsmanship.

Featuring a lab-grown diamond center measuring 10 by 5 millimeters, this ring reflects a commitment to ethical jewelry—minimizing environmental impact without sacrificing brilliance or quality.

Its slender silhouette suits hands that appreciate refined geometry and works beautifully alongside stackable bands or as a standalone statement. The low-profile design also fits comfortably under gloves or sleeves, making it a versatile choice for everyday life.
