Lab-Grown Diamond Engagement Ring

Light catches the elongated marquise center stone, its pointed ends drawing the eye along a graceful silhouette framed by a delicate halo. This semi-set engagement ring invites your choice of an 8 x 4 mm lab-grown diamond, ready to become a personal statement.

Crafted in warm 18K rose gold, the band’s subtle curve and low-profile halo setting ensure the ring sits comfortably for daily wear without catching. The polished finish and secure prong setting reflect meticulous hand inspection, balancing durability with refined elegance.

Each diamond is ethically sourced through lab-grown technology, reducing environmental impact while offering exceptional clarity and brilliance.

The slender band complements slender to medium finger sizes, with a design that layers effortlessly alongside wedding bands or stackable rings. Its low profile makes it glove-friendly and ideal for an active lifestyle.

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