Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 6 mm round diamond, poised to become the heart of a three-stone engagement ring that balances presence with subtlety. This semi-set design invites your choice of center stone, framed by two delicately crafted side diamonds set in cool 18K white gold, their shared prongs polished to a soft sheen that reflects the Brooklyn studio’s artisan touch.

The band’s slender profile and low-set shoulders ensure a comfortable fit for daily wear, while the smooth interior offers a quiet luxury beneath your hand. Each prong is meticulously hand-finished, securing stones with precision that honors both form and function.

Crafted with lab-grown diamonds, this ring embodies a commitment to ethical jewelry—minimizing environmental impact without compromising brilliance or clarity.

Ideal for those who appreciate a classic silhouette with a modern conscience, the three-stone setting complements a variety of hand shapes and pairs effortlessly with stacking bands or wedding rings. Its modest height slips easily beneath gloves and sleeves, making it a versatile choice for everyday life.
