Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 10 x 10 mm cushion diamond, its gentle glow poised to become the heart of your story. This semi-set engagement ring foundation in 18K white gold offers a sleek, modern-minimal silhouette, designed to highlight the stone’s subtle interplay of clarity and warmth.

Crafted with precision in Williamsburg, Brooklyn, the band’s clean lines and low-profile setting ensure everyday comfort without sacrificing presence. The cool white gold finish is polished to a refined sheen, balancing structure with a quiet confidence that complements the cushion’s vintage-inspired charm.

Each piece embraces lab-grown clarity, reflecting a commitment to ethical jewelry that honors both beauty and sustainability. The semi-set design invites your choice of a cushion-cut center diamond, allowing for a personalized selection that fits your vision.

Ideal for those who appreciate a refined aesthetic, this mounting suits hands seeking a balanced feel—neither bulky nor delicate—and pairs effortlessly with stacking bands or a solitaire style. Its comfort fit and modest height make it glove-friendly and practical for daily wear.

Resizing is available to ensure a perfect fit, and our Brooklyn studio welcomes you to explore the design process in person or online, where expert guidance meets thoughtful customization.
