Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with a subtle, elegant drama. This semi-set halo ring foundation in 14K white gold offers a delicate frame designed to amplify the center stone’s unique shape and brilliance.

Crafted in our Williamsburg studio, the band is hand-finished to a smooth comfort fit, ensuring it rests lightly against the skin for daily wear. The low-profile halo setting balances sparkle with practicality, making it glove-friendly and ideal for stacking alongside wedding bands or delicate stackable rings.

Each piece begins with ethically sourced lab-grown diamonds, chosen for clarity and sustainability, reflecting our commitment to responsible fine jewelry. The marquise cut, measuring 6 by 3.5 millimeters, lends a refined elongation to the hand, its vintage-inspired form reinterpreted through modern artisan techniques.

Should you wish to adjust sizing, our in-house jewelers provide careful resizing without compromising the ring’s integrity. Typical lead times accommodate custom design nuances, ensuring your ring is as unique as your story.
