Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of an oval diamond, its elongated silhouette casting a subtle glow that seems to stretch beyond the finger. This semi-set halo engagement ring foundation in 18K white gold offers a refined stage for a 7 x 5 mm oval center stone, designed to amplify the gem’s natural fire and elegance.

Crafted in our Williamsburg studio, the band is meticulously shaped for a smooth, comfort fit that sits low against the hand, making it ideal for daily wear. The halo setting, once completed with your chosen oval diamond, will surround the center with a delicate frame of smaller stones, enhancing brilliance without overwhelming the design. Each curve and prong is hand-finished to ensure durability and a polished surface that catches light from every angle.

Our commitment to sustainability is reflected in the exclusive use of lab-grown diamonds, offering clarity and sparkle with a significantly reduced environmental footprint. This ring’s slender profile and secure setting make it a versatile choice for those who appreciate understated elegance and a piece that layers effortlessly with other bands.

Whether you envision a solitaire oval or a halo-enhanced centerpiece, this semi-set ring invites you to personalize your engagement ring with expert guidance. Resizing is straightforward, and our Brooklyn studio welcomes you to explore options in person or begin your custom design journey online.
