Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc of brilliance that seems to stretch endlessly. This semi-set halo engagement ring in 14K white gold frames a 7 x 3.5 mm marquise center stone, inviting you to choose a lab-grown diamond that balances architectural grace with a whisper of vintage romance.

Crafted in Williamsburg, the setting features a finely milled halo that amplifies the diamond’s fiery facets while maintaining a low-profile design for everyday wear. The smooth, comfort-fit band curves gently beneath the finger, ensuring a secure yet effortless feel. Each piece is meticulously finished and inspected in-studio, reflecting a commitment to precision and subtle artistry.

Our lab-grown diamonds offer a clarity and sparkle indistinguishable from mined stones, with a significantly reduced environmental footprint. This ring suits those who appreciate a refined statement—its tapered shape elongates the hand, while the halo adds a soft glow that complements stacking or solo wear.

Should you need resizing, our Brooklyn studio provides expert adjustments without compromising the ring’s integrity. Typical lead times allow for thoughtful customization, ensuring your vision is realized with care.
