Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it carves a striking, tapered beam that draws the eye along the finger. This semi-set halo engagement ring in 18K white gold frames a 10 x 5 mm marquise center with a delicate circle of pavé stones, enhancing its dramatic shape without adding bulk.

Crafted with a low-profile setting, the ring balances architectural elegance and everyday comfort. The band’s smooth finish and subtle taper ensure it sits close to the finger, making it glove-friendly and ideal for stacking alongside wedding bands or personal favorites. Each piece is meticulously hand-finished in our Williamsburg studio, inspected for precision and durability.

Our commitment to ethical jewelry is reflected in the use of a lab-grown diamond, offering clarity and brilliance with a reduced environmental footprint.

Designed for those who appreciate refined geometry and a confident yet understated presence, this ring complements slender to medium finger shapes, emphasizing length and grace. The halo setting adds a soft glow that enhances the marquise’s signature sparkle without overwhelming its sleek form.

Should you need resizing or prefer a different center stone, our semi-set design allows for customization with ease, tailored to your vision.
