Lab-Grown Diamond Engagement Ring

When light catches the elongated curves of the marquise shape, it creates a subtle dance of brilliance that seems to stretch across the finger. This semi-set engagement ring offers a poised foundation in 18K white gold, crafted with a delicate balance of strength and grace to hold an 8 x 4 mm marquise diamond securely.

The slender band is polished to a satin-smooth finish, designed for everyday wear with a low-profile setting that slips comfortably beneath gloves or alongside other stackable rings. Each piece is meticulously hand-finished in our Williamsburg studio, ensuring precise prong placement and a refined silhouette that complements the stone’s tapered drama.

Choosing a lab-grown diamond here reflects a quiet commitment to sustainability, offering clarity and sparkle without compromise. The ring’s streamlined form suits those who appreciate architectural elegance and a refined, modern romance.

Should you wish to adjust the fit, resizing is handled expertly in-house to maintain the integrity of the design. Whether you bring your own marquise or explore our curated selection, this semi-set invites a personal touch.
