Lab-Grown Diamond Engagement Ring

Imagine the quiet moment when a square diamond catches the light, its sharp edges framed by a delicate halo that multiplies every flicker. This semi-set engagement ring foundation invites you to select a 7.5 x 7.5 mm center stone, ready to become the centerpiece of a finely crafted halo setting.

Handcrafted in 18K white gold, the band is shaped with a subtle comfort fit, its smooth interior designed for daily wear without fuss. The halo setting, meticulously soldered and polished in our Williamsburg studio, enhances the square diamond’s geometric clarity, creating a luminous frame that balances boldness with refined elegance.

Our commitment to lab-grown diamonds ensures a choice that honors both brilliance and sustainability, reflecting a modern approach to ethical jewelry.

Ideal for those who appreciate architectural precision and a low-profile silhouette, this ring suits hands that favor clean lines and a statement that remains understated. Its design accommodates stacking with wedding bands or complementary rings, while the semi-set nature allows for a personalized selection of the perfect square diamond.
