Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate dance of light that seems to stretch beyond the finger. This semi-set engagement ring invites you to select a 12 x 6 mm marquise center stone, its tapered points evoking a quiet elegance and subtle drama.

Crafted from warm 18K yellow gold, the band supports a five-stone arrangement that balances sparkle with refined restraint. The low-profile setting ensures the ring sits comfortably for daily wear, while the smooth finish reflects the meticulous handwork of our Williamsburg studio artisans.

Each lab-grown diamond offers clarity and brilliance with a conscientious footprint, aligning with a modern commitment to ethical jewelry. The slender band and gentle curve suit those who appreciate a graceful silhouette, ideal for stacking or wearing solo with ease.

Should you need resizing or prefer a different center stone cut, our in-studio consultations provide tailored guidance without pressure. Lead times are transparent, ensuring your custom design journey is as seamless as the ring’s polished surface.
