Lab-Grown Diamond Engagement Ring

Sunlight catches the 12mm round diamond’s facets, scattering a quiet dance of light across your hand. This semi-set solitaire ring invites you to select a center stone that will become the heart of your story.

Crafted from warm 18K yellow gold, the band’s smooth polish and gentle curve offer a comfortable fit that feels natural for daily wear. The low-profile setting balances security with subtlety, allowing the diamond’s brilliance to take center stage without overwhelming the finger.

Each piece is meticulously finished in our Williamsburg studio, where expert hands inspect every detail to ensure a refined, enduring design. The choice of a lab-grown diamond reflects a commitment to ethical jewelry, reducing environmental impact while maintaining exceptional clarity and sparkle.

This solitaire suits those who appreciate classic geometry with a modern sensibility—its round shape elongates the finger gracefully and pairs effortlessly with stacking bands or a wedding ring. The semi-set design offers flexibility, welcoming your personal selection of a diamond that resonates with your vision.

Should you need adjustments, resizing is available to ensure the ring fits comfortably over time. Our process is transparent and collaborative, designed to honor your pace and preferences.
