Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 12 x 12 mm cushion diamond, its gentle glow poised to become the centerpiece of a modern engagement. This semi-set ring foundation in 18K rose gold offers a warm, subtle contrast to the diamond’s glassy facets, while the white gold accents introduce a quiet architectural clarity.

Crafted in Williamsburg, Brooklyn, the band balances structure with comfort—its smooth interior designed for daily wear and effortless stacking. The low-profile setting ensures the ring sits close to the finger, making it glove-friendly and ideal for an active lifestyle. Each piece is meticulously finished and inspected in-studio, reflecting a commitment to precision and enduring beauty.

Our lab-grown diamonds provide a transparent origin and a smaller environmental footprint, aligning with a thoughtful approach to fine jewelry. This semi-set allows you to select a cushion cut stone that resonates personally, inviting a custom design experience tailored to your vision.

Resizing is available to ensure a perfect fit, with care instructions provided to maintain the band’s polished surface and the diamond’s brilliance over time. Whether you visit us in Williamsburg or start your design journey online, this ring foundation invites collaboration and confidence.
