Lab-Grown Diamond Engagement Ring

Sunlight catches the gently curved edges of this five-stone platinum semi-set, casting a quiet glow that promises moments yet to come. The 9 mm round center stone—known for its brilliant fire and balanced symmetry—awaits your choice, framed by four delicate side stones that enhance its luminous presence without overwhelming.

Crafted in cool platinum, the mounting offers a modern-minimal silhouette with clean lines and a low-profile setting that rests comfortably against the finger. Each prong is meticulously shaped and polished in our Williamsburg studio, ensuring durability and a refined finish that complements daily wear.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, offering clarity and sparkle with a reduced environmental footprint. This ring’s design suits those who appreciate structured elegance and desire a piece that layers seamlessly with other bands or stands confidently alone.

The semi-set format invites you to select a center stone that reflects your personal vision, with resizing available to ensure a perfect fit. Whether worn solo or stacked, the comfort fit band supports effortless wear from morning light to evening glow.
