Lab-Grown Diamond Engagement Ring

Imagine the quiet moment when light catches the elongated facets of a marquise diamond, casting a subtle, tapered glow across your hand. This semi-set solitaire ring invites you to select a center stone that measures 8 by 4 millimeters, its distinctive shape offering a graceful elongation that complements slender fingers with a hint of vintage drama.

Crafted from 18K white gold, the band is meticulously shaped in our Williamsburg studio, its smooth surface polished to a soft sheen that balances durability with everyday elegance. The low-profile setting ensures the ring sits comfortably beneath gloves or sleeves, while the secure prongs cradle your chosen diamond with artisan precision.

Each lab-grown diamond option reflects our commitment to ethical jewelry, offering clarity and brilliance without the environmental cost of traditional mining. This approach aligns with a sustainable ethos quietly embedded in every piece we create.

Designed for those who appreciate subtle sophistication, this solitaire suits hands that favor a refined silhouette and pairs effortlessly with stacking bands or a wedding ring. Its comfort fit and modest height make it a natural choice for daily wear, blending seamlessly with an active lifestyle.
