Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, confident shadow across the hand. This semi-set engagement ring invites you to choose a 10 x 5 mm center stone, its tapered points lending a striking architectural grace.

Crafted in warm 14K yellow gold, the band’s clean lines and subtle accent stones frame the marquise shape with modern-minimal clarity. The low-profile setting ensures the ring sits comfortably for daily wear, while the smooth finish reflects the meticulous hand-polishing done in our Williamsburg studio.

Each diamond is lab-grown, offering a transparent origin and a lighter environmental footprint without compromising brilliance or durability.

Designed for those who appreciate structure and refined confidence, this ring pairs effortlessly with stackable bands or stands alone as a statement of quiet elegance. Its slender profile suits slender to medium finger sizes, and the semi-set format allows you to select a stone that resonates personally.

Should you need resizing or advice on stone selection, our Brooklyn studio team is ready to guide you through a pressure-free process.
