Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a 4x4 mm square diamond, casting a quiet geometry of light across the skin. This solitaire semi-set invites you to choose a center stone that reflects your personal story, framed by a slender 18K yellow gold band that warms the design with subtle radiance.

Crafted in Williamsburg, the ring’s low-profile setting ensures the diamond sits close to the finger, blending comfort with everyday elegance. The polished finish enhances the smooth contour of the band, designed for effortless wear and gentle stacking alongside other favorites.

Each lab-grown diamond offers clarity and brilliance without compromise, embodying a commitment to ethical jewelry that respects both people and planet. The square cut’s clean lines bring a modern architectural grace, perfect for those drawn to precise form and quiet strength.

Ideal for hands that appreciate a refined silhouette, this solitaire balances presence with restraint, making it glove-friendly and easy to pair with wedding bands or stackable rings. Resizing is available to ensure a seamless fit, crafted with care in our Brooklyn studio.
