Lab-Grown Diamond Engagement Ring

Imagine the quiet confidence of a 10 x 10 mm cushion-shaped diamond poised to catch light with a soft, vintage glow—ready to become the centerpiece of your story. This semi-set solitaire mounting in 18K white gold offers a sleek, low-profile silhouette that rests comfortably against the finger, designed for everyday wear without sacrificing elegance.

Crafted in Williamsburg, Brooklyn, the band’s smooth finish and precise prong setting ensure the stone sits securely while allowing maximum light to enhance its gentle sparkle. The comfort fit shank curves subtly, making it easy to stack or wear solo with grace.

Each piece reflects our commitment to ethical jewelry: the mounting is tailored for a lab-grown diamond, combining sustainability with clarity and brilliance.

Ideal for those who appreciate refined craftsmanship and a modern yet understated presence, this setting complements the cushion’s soft edges and balanced proportions, flattering a variety of hand shapes and sizes.
