Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that seems to stretch beyond the hand. This semi-set engagement ring invites you to choose a 7 x 3.5 mm marquise center stone, its pointed ends evoking a quiet drama and refined elegance.

Crafted in warm 14K yellow gold, the slender band is designed for everyday grace, with a low-profile setting that rests close to the finger. The polished finish enhances the metal’s soft glow, while the secure prong structure ensures your chosen diamond is held with delicate precision. Each ring is finished by hand in our Williamsburg studio, where comfort and wearability are paramount.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both ethical sourcing and environmental mindfulness.

This solitaire silhouette suits those who appreciate a statement that is both bold and intimate—ideal for slender fingers or as a striking contrast when stacked with textured bands. Its low profile makes it glove-friendly and unobtrusive for daily wear.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit without compromising the ring’s integrity.
