Lab-Grown Diamond Engagement Ring

Morning light catches the delicate curve of a 3.4 mm round diamond, its facets whispering quiet brilliance against the soft glow of 18K white gold. This solitaire semi-set invites you to choose a center stone that reflects your story, framed by a slender band that balances presence with subtlety.

Crafted in Williamsburg, Brooklyn, the band’s polished finish and gently tapered shank ensure a comfortable fit for daily wear. The low-profile setting keeps the diamond close to the hand, making it glove-friendly and ideal for stacking alongside meaningful bands.

Each piece embraces the clarity and sustainability of lab-grown diamonds, a conscious choice that honors both beauty and ethics. The round shape offers classic fire and sparkle, a quiet yet confident expression of enduring affection.

Designed for those who appreciate refined craftsmanship and personal expression, this semi-set allows you to select a center stone that suits your vision and lifestyle. Resizing is available to ensure a perfect fit, with every ring finished and inspected in-studio for lasting quality.
