Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise center, casting a slender beam of light that dances with every movement. This semi-set halo engagement ring in 14K yellow gold frames a 12 x 6 mm marquise diamond, its tapered shape lending a graceful, almost poetic silhouette.

Crafted with precision in Williamsburg, the band’s warm gold hue is polished to a soft glow, complementing the halo setting designed to amplify brilliance without overwhelming the finger. The low-profile mounting ensures comfort for daily wear, while the secure prongs cradle the stone delicately yet firmly.

Each lab-grown diamond is chosen for clarity and ethical provenance, reflecting a commitment to sustainability without compromise. The marquise’s distinctive shape elongates the hand, ideal for those seeking a ring that balances boldness with refined elegance.

Its slender band pairs effortlessly with stacking rings or stands alone as a statement of quiet romance. The semi-set design invites you to select a center stone that resonates personally, making the piece uniquely yours.
