Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a confident, architectural gleam. This semi-set engagement ring in 14K white gold offers a sleek foundation designed to showcase a 9 x 4.5 mm marquise center stone, framed by delicate accent diamonds that enhance its modern-minimal clarity.

Crafted with precision in Williamsburg, Brooklyn, the band features a low-profile setting that balances elegance with everyday wearability. The smooth finish and comfort fit ensure it rests lightly on the finger, while the secure prong structure protects the pointed ends of the marquise shape without adding bulk.

Each ring is thoughtfully made using lab-grown diamonds, reflecting a commitment to ethical jewelry that reduces environmental impact without compromising brilliance or clarity.

Ideal for those who appreciate clean lines and architectural form, this mounting suits slender to medium finger sizes and pairs beautifully with stackable bands or a simple wedding band. Its subtle height makes it glove-friendly and practical for daily life.

Resizing is available to ensure a perfect fit, and the semi-set design invites you to select a center stone that resonates personally, with expert guidance from our Brooklyn studio.
