Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate dance of light that seems to stretch beyond the finger. This three-stone semi-set engagement ring in 18K rose gold frames a 10 x 5 mm marquise center, its tapered points echoing a quiet elegance with a hint of vintage romance.

Crafted in Williamsburg, Brooklyn, the warm blush of the rose gold band is hand-finished to a smooth comfort fit, designed for everyday wear without catching or discomfort. The three-stone setting balances presence with subtlety, allowing the marquise’s signature brilliance to shine alongside two gently flanking stones, all ready to be set with your choice of center diamond.

Each lab-grown diamond is selected for clarity and light performance, reflecting our commitment to ethical jewelry that honors both beauty and sustainability. The low-profile mounting keeps the ring glove-friendly and stackable, ideal for those who appreciate refined details without excess height.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure a seamless fit, with careful inspection at every stage. Typical lead times for custom setting completion are shared during consultation, making the process transparent and pressure-free.
