Lab-Grown Diamond Engagement Ring

Light catches the marquise diamond’s elongated silhouette, casting a delicate shimmer that seems to stretch beyond the finger. This semi-set solitaire invites you to select a 7 x 3.5 mm lab-grown marquise, whose tapered points and graceful curve evoke a quiet drama.

Crafted in warm 14K rose gold, the mounting’s slender prongs cradle the stone with precision, while the polished white gold band offers a subtle contrast and a gentle gleam. The low-profile setting ensures everyday comfort, slipping easily beneath gloves or alongside stackable bands.

Each ring is finished by hand in our Williamsburg studio, where expert jewelers inspect every detail to balance durability with refined elegance. The lab-grown diamond at its heart reflects a commitment to ethical jewelry, reducing environmental impact without sacrificing brilliance.

Designed for those who appreciate romantic understatement, this solitaire suits slender to medium fingers, enhancing the hand’s natural lines with its elongated shape. Its semi-set form allows you to personalize the centerpiece, making the ring uniquely yours.
