Lab-Grown Diamond Engagement Ring

Soft light catches the gently rounded corners of a 5x5 mm cushion diamond, poised to become the heart of a halo setting that amplifies its vintage-inspired glow. This semi-set engagement ring foundation invites your choice of a lab-grown center stone, nestled within a finely crafted 18K white gold band that balances subtlety with presence.

Hand-forged in our Williamsburg studio, the band’s smooth profile and delicate halo setting are designed for everyday wear—comfortably low-profile yet visually arresting. Each curve is polished to a satiny finish, ensuring the ring feels as refined to the touch as it looks in the light. The halo’s micro-pavé setting enhances brilliance without adding bulk, making it glove-friendly and ideal for stacking with complementary bands.

Our commitment to ethical jewelry is reflected in the clarity and sustainability of the lab-grown diamond options this semi-set accommodates, offering a conscious alternative without compromise on sparkle or character.

Perfect for those who appreciate artisan craftsmanship and a design that bridges classic charm with modern sensibility, this ring suits a variety of hand shapes and sizes, especially those seeking a balance between statement and subtlety.
