Lab-Grown Diamond Engagement Ring

When sunlight catches the sharp edges of a square diamond, it fractures into a quiet dance of light and shadow—an intimate moment of geometry and glow. This semi-set solitaire ring offers a poised foundation for a 7.5 x 7.5 mm square center stone, its clean lines inviting a modern yet timeless centerpiece.

Crafted in warm 10K rose gold, the band’s gentle curve balances softness with structure, while the low-profile setting ensures everyday ease without sacrificing presence. Each ring is meticulously finished by hand in our Williamsburg studio, polished to a satin sheen that complements the diamond’s crisp facets.

Our commitment to lab-grown diamonds means this piece carries clarity and brilliance with a lighter environmental footprint, reflecting a thoughtful approach to fine jewelry.

Designed for those who appreciate subtle strength, the ring’s slender band feels comfortable beneath the hand and pairs effortlessly with stacking bands or a wedding band. Its semi-set nature allows you to select a square diamond that speaks to your personal story.

Should you need resizing, our in-studio artisans handle adjustments with care to maintain the ring’s integrity and finish.
