Lab-Grown Diamond Engagement Ring

Imagine the gentle elongation of an oval diamond catching light with every subtle movement of the hand. This semi-set halo ring foundation in 18K white gold is crafted to showcase a 12 x 10 mm oval center stone of your choosing, offering a refined balance between presence and wearability.

The band’s low-profile setting ensures it sits comfortably beneath gloves or daily wear, while the halo setting promises a delicate frame that amplifies brilliance without bulk. Each piece is meticulously finished in our Williamsburg studio, polished to a smooth comfort fit that feels as natural as it looks.

Our commitment to lab-grown diamonds means your ring carries a clarity and ethical transparency that aligns with modern values, reducing environmental impact without compromising on beauty.

This mounting suits those who appreciate architectural elegance with a subtle vintage nod, perfect for hands that favor a graceful silhouette and a ring that layers effortlessly with other bands.
