Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 10 x 10 mm cushion diamond, its gentle glow poised between vintage warmth and modern clarity. This semi-set three-stone ring foundation in 18K white gold offers a structured yet understated frame, designed to showcase your choice of center stone with architectural precision.

Crafted in Williamsburg, the band’s sleek profile balances strength with comfort, its polished finish reflecting subtle light without overwhelming daily wear. The three-stone setting provides a harmonious symmetry, ideal for those who appreciate clean lines and confident minimalism. Each piece undergoes meticulous hand inspection to ensure flawless assembly and enduring wearability.

Our commitment to lab-grown diamonds means your ring carries a clear ethical edge—sustainably sourced with a reduced environmental footprint, without compromising brilliance or clarity.

With a low-profile setting and smooth shank, this ring suits hands seeking elegance without bulk, stacking effortlessly alongside wedding bands or worn solo for quiet sophistication. The semi-set design invites personal choice, allowing you to select a cushion-cut diamond that reflects your unique story.

Resizing is available to ensure a precise fit, crafted with care in our Brooklyn studio to accommodate your daily life comfortably.
