Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, its tapered points drawing the eye along the finger with quiet drama. This semi-set halo engagement ring foundation in 14K yellow gold offers a warm, buttery glow that complements the stone’s sharp geometry.

Handcrafted in our Williamsburg studio, the band is shaped for comfort with a subtle curve that sits close to the skin, while the halo setting is designed to enhance the center’s 8 x 4 mm marquise shape without adding bulk. Each prong is meticulously finished to secure your chosen diamond with precision and care.

Our commitment to sustainability is reflected in the lab-grown diamond clarity this mounting is crafted to showcase—ethical jewelry that honors both beauty and responsibility.

The low-profile design suits those who prefer a ring that layers effortlessly with wedding bands or stacks with other favorites, while the narrow shank ensures it feels balanced on slender or average-sized hands.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit without compromising the ring’s integrity.
