Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, luminous shadow across the hand. This semi-set solitaire ring invites you to select a center stone that echoes your unique story, framed by a warm 14K yellow gold band crafted with deliberate care in our Williamsburg studio.

The band’s smooth, gently rounded profile offers a comfortable fit for daily wear, while the low-profile setting keeps the diamond close to the finger, minimizing snagging. Each curve is hand-finished to a soft sheen, reflecting the artisan’s touch in every detail.

Our commitment to sustainability shines through the choice of lab-grown diamonds, offering clarity and brilliance without compromise. This ethical approach aligns with a modern lifestyle that values both beauty and responsibility.

Designed for those who appreciate subtle drama, the marquise shape elongates the finger with its tapered points, balancing boldness and elegance. Its solitaire style stands alone with quiet confidence, perfect for stacking or wearing solo.

Should you need resizing or prefer a custom stone selection, our Brooklyn studio offers personalized consultations to ensure your ring fits seamlessly into your life.
