Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender shadow that dances along the finger. This semi-set engagement ring invites you to select a 12 x 6 mm marquise stone, whose tapered silhouette lends a graceful drama and visually lengthens the hand.

Crafted from warm 10K yellow gold, the band is shaped and polished in our Williamsburg studio with artisan precision. Its low-profile setting balances security with subtlety, while delicate accent stones frame the center, enhancing light play without overwhelming the design. The smooth finish and modest width ensure a comfortable daily wear experience.

Each lab-grown diamond offers clarity and brilliance with a smaller environmental footprint, reflecting our commitment to ethical jewelry. The ring’s design suits those who appreciate refined geometry and a piece that layers effortlessly with other bands or stands alone with quiet confidence.

Should you need resizing or prefer a custom accent arrangement, our Brooklyn studio welcomes consultations to tailor the ring to your lifestyle and vision. Typical lead times reflect careful handcrafting rather than mass production.
