Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful arc. This semi-set three-stone engagement ring foundation in 14K yellow gold invites your choice of a 9 x 4.5 mm center stone, ready to become a personal emblem of commitment.

Handcrafted in our Williamsburg studio, the band’s warm yellow gold is shaped with subtle tapering to cradle side stones securely while maintaining a low-profile silhouette. The artisan finish reveals delicate hand polishing that softens edges for a comfortable fit, ideal for daily wear without catching or bulk.

Each lab-grown diamond option offers clarity and brilliance with a smaller environmental footprint, reflecting a mindful approach to fine jewelry. The marquise cut’s distinctive shape elongates the finger, pairing beautifully with slender hands or stacked bands for a layered look.

Designed for those who appreciate understated elegance and a ring that moves seamlessly from studio to street, this setting balances presence with wearability. Resizing is available to ensure a precise fit, crafted with care to preserve the integrity of the design.
