Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc across the finger. This three-stone semi-set engagement ring in 18K rose gold invites you to choose a center stone that will become the heart of a quietly poetic story.

Crafted in warm rose gold, the gently curved band supports two smaller side stones that frame the marquise’s signature tapered drama. The low-profile setting balances presence with everyday ease, while the smooth finish ensures a comfortable fit for daily wear. Each piece is meticulously hand-finished in our Williamsburg studio, where precision meets subtle artistry.

Our diamonds are lab-grown, offering clarity and brilliance with a mindful approach to sustainability and ethical sourcing.

This ring suits those who appreciate refined romance and a silhouette that elongates the hand, pairing beautifully with stackable bands or worn solo. Its modest height makes it glove-friendly and ideal for an active lifestyle.

Should you wish to adjust sizing, our Brooklyn studio offers expert resizing to ensure a perfect fit without compromising design integrity.
