Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow across the hand. This semi-set halo engagement ring in 18K yellow gold frames a 10 x 5 mm marquise center with a delicate circle of pavé stones, amplifying its sculptural elegance.

Crafted in Williamsburg, the band’s smooth, low-profile shank ensures comfortable daily wear, while the halo setting balances brilliance with subtlety. Each piece is meticulously finished by hand, polished to a soft glow, and inspected for precision before it leaves the studio.

Choosing a lab-grown diamond means embracing clarity and sustainability without compromise—this ring reflects a commitment to ethical jewelry that honors both beauty and responsibility.

The marquise shape’s tapered points visually elongate the finger, making it an ideal choice for those who appreciate refined geometry and confident minimalism. Its semi-set nature invites you to select a center stone that resonates personally, offering a bespoke experience tailored to your vision.

Resizing is available to ensure a perfect fit, and the low-profile design pairs effortlessly with stacking bands or a wedding ring.
