Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond, casting a slender beam that dances across the hand with quiet confidence. This three-stone engagement ring balances architectural clarity with modern minimalism, its 12 x 6 mm center stone framed by two delicate side diamonds.

Crafted in 14K white gold, the band is polished to a soft sheen that complements the sharp facets of the marquise cut. The low-profile setting ensures the ring sits comfortably for daily wear, while the secure prong mount highlights the diamond’s tapered drama without excess metal.

Each lab-grown diamond is selected for exceptional clarity and brilliance, reflecting a commitment to sustainable, ethical jewelry without compromise on sparkle or presence.

Designed for those who appreciate structured elegance, this ring’s slender silhouette elongates the finger and pairs effortlessly with stacking bands or a wedding band. Its refined profile also fits comfortably under gloves or sleeves, making it a versatile choice for everyday life.

Should you need a custom size, resizing is handled with care in our Williamsburg studio, ensuring a perfect fit without altering the ring’s clean lines.
