Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a slender, dramatic silhouette that feels both bold and intimate. This semi-set three-stone ring invites you to select a center stone that measures 9 by 4.5 millimeters, its tapered shape naturally elongating the finger with architectural grace.

Crafted from warm 14K rose gold, the band is shaped and finished in our Williamsburg studio with a subtle comfort fit that rests gently against the skin. The three-stone setting balances presence with wearability, designed to sit low enough for everyday ease while showcasing the center stone’s distinctive profile alongside two delicate side gems.

Each piece reflects our commitment to ethical jewelry: the ring is ready to embrace a lab-grown diamond, offering clarity and brilliance with a smaller environmental footprint. The rose gold’s soft glow complements the marquise’s vintage-inspired drama, making it a thoughtful choice for those who appreciate artisan craftsmanship and sustainable values.

Ideal for hands that favor elongated shapes or those seeking a ring that layers well with wedding bands, this design is glove-friendly and comfortable for daily wear. Should you need resizing or prefer a custom consultation, our Brooklyn studio welcomes you to explore options with no pressure and full transparency.
