Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of an 8x4 mm marquise diamond, it reveals a striking balance of drama and elegance, a shape that naturally elongates the finger with its tapered points. This semi-set halo engagement ring offers a refined foundation, ready to showcase your chosen center stone surrounded by a delicate halo that enhances brilliance without overwhelming the design.

Crafted in 18K white gold, the mounting features a low-profile setting designed for everyday wear, with secure prongs that keep the stone close to the finger for comfort and practicality. The band’s smooth finish and subtle width ensure it slips easily beneath gloves and stacks effortlessly with wedding bands or other rings.

Each piece is meticulously hand-finished in our Williamsburg studio, where expert jewelers inspect every detail to meet exacting standards of fit and finish. The choice of lab-grown diamond aligns with a commitment to ethical jewelry, offering clarity and sparkle with a reduced environmental footprint.

This ring suits those who appreciate architectural grace paired with modern functionality—ideal for hands that value both statement and subtlety. The semi-set design invites personalization, allowing you to select a marquise diamond that reflects your unique story.

Resizing is available to ensure a precise fit, and our team is happy to guide you through care recommendations to maintain the ring’s brilliance over time.
