Lab-Grown Diamond Engagement Ring

Imagine the soft glow of a 5 x 5 mm cushion-cut diamond poised to catch the light with a gentle vintage shimmer, ready to become the heart of your custom engagement ring. This semi-set foundation in 18K rose gold offers a warm, subtle contrast to the diamond’s glassy facets, while the white gold accents introduce a crisp architectural edge, balancing modern minimalism with quiet confidence.

Crafted in Williamsburg, Brooklyn, the band is designed with a low-profile setting that sits comfortably for daily wear, its smooth finish inviting touch without catching on fabric. The interplay of rose and white gold is carefully polished to reveal a refined structure, emphasizing clarity and precision in every angle.

Each ring begins with a lab-grown diamond, chosen for its ethical clarity and sustainable origin, reflecting a commitment to responsible luxury without compromise.

This design suits those who appreciate subtle complexity—a ring that pairs effortlessly with stacking bands or stands alone with quiet strength. Its moderate size and balanced shape complement a variety of hand sizes, while the semi-set style allows you to select a center stone that resonates personally.

Resizing is straightforward, handled in-studio with care to maintain the integrity of the mixed-metal finish and setting.
