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 in warm 14K rose gold, this solitaire mounting is shaped by skilled hands in our Williamsburg studio. The band’s gentle taper and low-profile setting ensure a comfortable fit for daily wear, while the smooth finish reflects the artisan’s attention to detail. The mounting’s minimalist design allows the marquise to take center stage, supported by secure prongs that cradle the stone without overwhelming it.

Each ring embraces the clarity and sustainability of lab-grown diamonds, aligning with a modern ethical approach to fine jewelry. This piece suits those who appreciate refined geometry and a ring that feels as natural as it looks—ideal for stacking or wearing solo with ease.

Should you need adjustments, resizing is available to ensure a perfect fit, crafted with the same care as the original design. Lead times reflect our commitment to handcrafting each piece thoughtfully in Brooklyn.
