Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow across the hand. This semi-set engagement ring invites you to select a 10 x 5 mm marquise stone, whose tapered points and graceful curves evoke a quiet drama and elongate the finger with subtle elegance.

Crafted from warm 10K yellow gold, the band is shaped and finished in our Williamsburg studio with a delicate artisan touch. The low-profile setting is designed for everyday wear, balancing secure prongs with a refined silhouette that slips comfortably beneath gloves or rings stacked alongside it.

Each piece is thoughtfully inspected to ensure smooth edges and a polished surface that feels as inviting as it looks. The choice of a lab-grown diamond center reflects a commitment to sustainable, ethical jewelry without compromise on brilliance or clarity.

Ideal for those who appreciate a blend of classic form and handcrafted detail, this ring suits hands that favor slender shapes and a touch of vintage-inspired geometry. Its semi-set nature offers flexibility, allowing you to select a stone that resonates personally.

Should you need resizing or guidance on stone selection, our Brooklyn studio offers personalized consultations with no pressure and clear timelines.
