Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to stretch the hand with quiet elegance. This semi-set halo engagement ring in 14K yellow gold frames a 9 x 4.5 mm marquise center, inviting you to select a stone that balances brilliance with graceful drama.

Crafted in Williamsburg, the band’s warm gold hue is polished to a soft glow, while the halo setting enhances the diamond’s slender shape with a ring of smaller stones, amplifying light without overwhelming the profile. The low-set design ensures comfort for daily wear, slipping easily beneath gloves or alongside stackable bands.

Each piece reflects a commitment to ethical sourcing through lab-grown diamonds, offering clarity and sparkle with a reduced environmental footprint. The semi-set approach allows for personal choice in the center stone, making this ring a truly bespoke expression of love.

Ideal for those who appreciate a blend of vintage-inspired romance and modern craftsmanship, this ring suits slender fingers and elongates the hand’s natural lines. Its subtle height and smooth edges make it a practical yet poetic companion for everyday moments.
