Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 7 mm round diamond, poised to become the centerpiece of a three-stone engagement ring. This semi-set foundation in warm 18K yellow gold awaits your choice of lab-grown center stone, crafted with precision in our Williamsburg studio.

The band’s artisan finish reveals subtle hammer marks, a tactile reminder of hand-forged care. Its low-profile setting ensures the ring sits comfortably for daily wear, while the three-stone layout balances classic symmetry with modern grace. Each prong is meticulously shaped to cradle your diamond securely, polished to a soft sheen that complements the gold’s natural glow.

Our lab-grown diamonds offer a clarity and brilliance that honors both beauty and sustainability, reflecting a commitment to ethical jewelry without compromise.

Designed for those who appreciate understated elegance, this ring’s slender band fits seamlessly alongside wedding bands or stackable rings. Its modest height makes it glove-friendly and ideal for active hands.

Should you need resizing, our Brooklyn workshop provides expert adjustments to ensure a perfect fit without disrupting the ring’s integrity.
