Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a delicate shimmer that seems to stretch beyond the fingertips. This three-stone semi-set engagement ring in 14K rose gold frames an 8 x 4 mm marquise center, its pointed curves echoing a quiet drama and refined elegance.

Each band is meticulously crafted in Williamsburg, where the warm rose gold is hand-finished to a soft, satiny glow that complements the diamond’s sharp geometry. The low-profile setting ensures the ring rests comfortably against the hand, while the three-stone design adds subtle depth without overwhelming daily wear.

Our diamonds are lab-grown, offering a clarity and brilliance born from sustainable practices, reflecting a commitment to ethical jewelry without compromise.

Designed for those who appreciate a blend of vintage-inspired romance and modern sensibility, this ring suits slender to medium finger shapes and layers gracefully with other bands. Its comfort fit and modest height make it glove-friendly and ideal for everyday life.

Should you wish to adjust sizing, our Brooklyn studio provides expert resizing to maintain the integrity of the design.
