Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a cushion diamond, its gentle glow unfolding like a whispered promise. This three-stone semi-set engagement ring in 18K white gold offers a poised foundation for an 8 x 8 mm center stone, inviting your choice to complete its artisan-crafted story.

Hand-forged in Williamsburg, the band’s smooth, low-profile silhouette balances presence with everyday ease. Each prong is meticulously shaped to cradle the cushion cut’s delicate facets, enhancing its vintage-inspired warmth while ensuring secure wear. The polished finish reflects subtle light, complementing the diamond’s soft brilliance without overwhelming it.

Crafted with lab-grown diamonds, this piece honors a commitment to ethical jewelry—minimizing environmental impact while maximizing clarity and sparkle.

Designed for those who appreciate refined comfort, the ring’s gentle curve fits naturally on the finger and pairs effortlessly with stacking bands or a wedding band. Its modest height allows for glove-friendly wear and daily life without interruption.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit without compromising the ring’s integrity.
