Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 7mm round diamond, poised to become the heart of a three-stone engagement ring. This semi-set foundation, crafted from warm 10K yellow gold, invites your choice of lab-grown center stone, ready to reflect your unique story.

Each band is shaped and polished in our Williamsburg studio, where the artisan’s hand ensures a smooth, comfort-fit profile that rests lightly against the skin. The three-stone setting balances presence with subtlety, designed for daily wear without catching or discomfort.

Our diamonds are lab-grown with clarity and brilliance equal to mined stones, offering an ethical alternative that honors both beauty and sustainability. The warm yellow gold complements a variety of skin tones, while the low-profile setting keeps the ring glove-friendly and stackable alongside wedding bands or personal treasures.

Should you need resizing, our in-house jewelers provide precise adjustments to maintain the ring’s seamless silhouette. Typical lead times reflect the care invested in each custom design, ensuring a piece made for a lifetime.
