Lab-Grown Diamond Engagement Ring

When sunlight catches the sharp edges of a 9 x 9 mm square diamond, it fractures into a quiet dance of light and shadow—an intimate moment of geometry and glow. This five-stone semi-set engagement ring foundation in 18K white gold offers a refined stage for your chosen center stone, its clean lines framing brilliance with architectural grace.

Crafted in Williamsburg, the band is polished to a satin finish that feels smooth against the skin, designed for daily wear with a low-profile setting that slips comfortably beneath gloves or alongside stackable bands. Each prong is meticulously shaped to secure your stone while maintaining an elegant silhouette.

Our commitment to lab-grown diamonds ensures clarity and sparkle without compromise, reflecting a sustainable approach to fine jewelry that honors both craftsmanship and conscience.

This ring suits those who appreciate modern geometry paired with subtle romance—its square shape lends a poised, contemporary edge that elongates the finger and complements a variety of personal styles.
