Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of an 8 x 8 mm cushion diamond, casting a gentle glow that feels like a quiet promise. This solitaire semi-set ring pairs the warmth of 18k yellow and 18k yellow and platinum with the cool strength of 18k yellow and platinum, a fixed two-tone band that frames the stone with subtle contrast and enduring grace.

Crafted with a low-profile setting, the diamond sits close to the finger, offering a comfortable wear that suits daily life without sacrificing presence. The band’s smooth finish and balanced weight make it easy to stack or wear solo, while the cushion cut’s soft vintage glow lends a romantic depth to the design.

Each ring is hand-finished in our Williamsburg studio, where precision meets quiet artistry. The semi-set mounting allows you to select a lab-grown diamond of your choice, ensuring ethical clarity and sustainability without compromise.

Designed for those who appreciate a blend of classic romance and modern craftsmanship, this ring complements a variety of hand shapes and sizes, its comfort fit inviting endless wear. The low profile also makes it glove-friendly, ideal for everyday moments and special occasions alike.

Resizing is available to ensure a perfect fit, and our team is happy to guide you through the selection and design process with care and expertise.
