Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous beam that seems to stretch beyond the hand. This semi-set engagement ring invites you to choose a 7 x 3.5 mm marquise stone, whose pointed ends and graceful curves evoke a refined sense of modern geometry and confident clarity.

Crafted in 14K yellow or white gold, the mounting features delicate accent stones that frame the center with subtle brilliance. The setting balances structure with wearability—its low profile and smooth band ensure comfort for daily life, while the precise finish reflects careful hand inspection in our Williamsburg studio.

Each diamond is lab-grown, offering a transparent origin and a smaller environmental footprint without compromising on optical purity or sparkle.

Designed for those who appreciate architectural elegance, this ring suits slender fingers and pairs effortlessly with stackable bands or a wedding band of your choice. Its semi-set nature allows you to select a center stone that resonates personally, making the design uniquely yours.

Should you need resizing or guidance on selecting the ideal marquise cut, our Brooklyn studio team is ready to assist with thoughtful care and expertise.
