Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow that dances across the hand. This three-stone semi-set engagement ring in 18K yellow gold frames a 12 x 6 mm marquise center, its pointed ends drawing the eye along the finger’s natural line.

Each band is hand-shaped in our Williamsburg studio, polished to a soft glow that complements the warm gold’s depth. The three-stone setting balances presence with wearability, designed for everyday grace without catching or bulk. The low-profile mounting ensures comfort beneath gloves or layered alongside other bands.

Our diamonds are lab-grown with precision, offering clarity and brilliance while honoring a commitment to sustainable, ethical jewelry practices.

This ring suits those who appreciate architectural elegance paired with artisanal craftsmanship—perfect for hands that favor slender, elongated shapes or for stacking with a slim wedding band. The semi-set design invites you to select a marquise diamond that reflects your personal story.

Resizing is available to ensure a seamless fit, crafted with care to maintain the ring’s refined silhouette.
