Lab-Grown Diamond Engagement Ring

The elongated silhouette of the 7 x 3.5 mm marquise diamond promises a subtle drama, drawing the eye along its tapered points with a refined elegance. This semi-set engagement ring foundation in 14K white gold offers a sleek, low-profile frame designed to sit comfortably beneath the hand, minimizing catch and maximizing everyday ease.

Crafted in Williamsburg, Brooklyn, the band’s smooth finish and precise accents ensure a balanced wear, ideal for stacking or solo presentation. The setting’s engineering prioritizes durability without sacrificing the delicate visual line of the marquise shape, while the white gold’s cool tone complements the stone’s clarity and fire.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that reduce environmental impact without compromising brilliance or quality.

Its modest height and comfort fit make this mounting well-suited for those seeking a ring that integrates seamlessly with daily life, including glove wear and layered styling. The semi-set design invites you to select a center stone that resonates personally, allowing customization within a trusted framework.

Resizing is straightforward, handled in-studio with care to maintain the band’s integrity and finish.
