Lab-Grown Diamond Engagement Ring

Imagine the gentle curve of a marquise diamond catching the soft morning light, its elongated silhouette tracing a delicate arc across your finger. This semi-set engagement ring invites you to choose a center stone measuring 12 by 6 millimeters, a shape known for its graceful taper and subtle drama.

Crafted in warm 18K rose gold, the mounting’s slender prongs cradle the stone with quiet precision, while the polished white gold band offers a cool contrast that enhances the diamond’s brilliance. The low-profile setting ensures everyday comfort, slipping easily beneath gloves or alongside stackable bands without catching.

Each piece is meticulously finished and inspected in our Williamsburg studio, where expert hands shape and refine every curve to balance elegance with durability. The choice of a lab-grown diamond reflects a commitment to ethical jewelry, reducing environmental impact without compromising on clarity or fire.

This solitaire design suits those who appreciate romantic understatement paired with modern craftsmanship—ideal for slender to medium finger sizes, where the marquise’s elongation visually lengthens the hand. Its versatile silhouette complements both minimalist and layered looks.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as natural as it looks. Lead times vary slightly depending on stone selection but we guide you through each step with care.
