Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its pointed ends drawing the eye along the finger with subtle drama. This semi-set engagement ring features a 9 x 4.5 mm marquise center, designed to balance presence with everyday ease.

Crafted in warm 14K rose gold, the band is finished with a smooth comfort fit and a low-profile setting that tucks close to the hand, minimizing snagging during daily wear. The mounting is prepared to showcase your chosen marquise stone, framed by delicate accent details that enhance the diamond’s natural brilliance without overwhelming it.

Each piece is meticulously inspected in our Williamsburg studio, where precision meets thoughtful design to ensure durability and refined wearability. The rose gold’s subtle blush complements a variety of skin tones, while the semi-set style invites personal selection of a lab-grown diamond with clarity and sparkle tailored to your vision.

Lab-grown diamonds offer a clear ethical advantage, reducing environmental impact while maintaining the radiance and structural integrity of mined stones.

This ring suits those who appreciate architectural elegance paired with practical comfort—a low-profile silhouette that layers beautifully with wedding bands or stands confidently alone. Its dimensions and setting style make it glove-friendly and ideal for active lifestyles.
