Lab-Grown Diamond Engagement Ring

Morning light catches the subtle sparkle of a 5.5 mm round diamond poised to become the heart of a three-stone engagement ring. This semi-set design invites your choice of center stone, framed by two delicately crafted side stones that balance brilliance with architectural grace.

Hand-forged in 18K white gold, the band carries a refined comfort fit, its smooth interior contouring gently to the finger. The setting’s low profile ensures everyday wearability without sacrificing the dance of light across each facet, while expert finishing reveals a soft, satiny sheen that complements the diamond’s fire.

Each lab-grown diamond embodies clarity and sustainability, reflecting a commitment to ethical jewelry that honors both beauty and conscience.

Ideal for those who appreciate a classic silhouette with a modern twist, this ring suits slender to medium finger shapes and layers effortlessly with stackable bands or wedding bands. Its modest height makes it glove-friendly and practical for daily life.

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