Lab-Grown Diamond Engagement Ring

Imagine the gentle curve of a 14K yellow gold band warming your finger, its soft glow cradling a luminous round diamond nearly an inch across. This solitaire semi-set invites you to select a center stone between 11.75 and 12.1 millimeters, promising a radiant focal point that captures light with classic brilliance.

Handcrafted in Williamsburg, Brooklyn, the band features a comfort fit profile that molds seamlessly to daily wear. Six slender prongs rise with delicate precision, securing your chosen diamond while maintaining a low profile that slips easily beneath gloves or alongside stackable rings. Each piece is meticulously finished and inspected in-studio, ensuring a smooth, tactile experience that balances strength with elegance.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and sparkle with a smaller environmental footprint.

This design suits those who appreciate refined simplicity and a substantial presence without excess bulk—ideal for hands that favor understated luxury and versatile styling.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit without compromising the band’s sleek silhouette.
