Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that seems to stretch across the hand like a whispered promise. This semi-set solitaire invites you to select a 6 x 3 mm lab-grown marquise, its pointed ends evoking subtle drama and refined elegance.

Crafted in warm 18K yellow gold, the mounting balances classic allure with modern precision. The slender prongs cradle the stone securely while maintaining a low profile, allowing the diamond’s shape to take center stage without bulk. The band’s gentle curve and polished finish ensure a comfortable fit for daily wear, whether worn solo or paired with a wedding band.

Each piece is meticulously finished in our Williamsburg studio, where expert hands inspect every detail to meet exacting standards. The ethical clarity of the lab-grown diamond reflects a commitment to sustainability without compromise.

Ideal for those who appreciate a ring that feels as intimate as it looks—its slim profile and smooth edges make it glove-friendly and easy to stack. The marquise shape elongates the finger, lending a graceful, architectural line that suits a variety of hand sizes.

Should you wish to adjust the band size, resizing is available to ensure a perfect fit without altering the ring’s elegant silhouette.
