Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 13 x 13 mm cushion diamond, casting a gentle glow that feels both intimate and enduring. This semi-set solitaire ring invites you to select a center stone that speaks to your story, framed by a warm 14K yellow gold band that balances classic warmth with modern refinement.

Crafted in Williamsburg, Brooklyn, the band’s smooth profile and subtle taper ensure a comfortable fit for daily wear, while the low-set prongs cradle the stone securely without overwhelming its vintage-inspired silhouette. Each piece is meticulously finished by hand, polished to a satin sheen that complements the diamond’s soft brilliance.

Choosing a lab-grown diamond here means embracing clarity and sustainability without compromise—ethical jewelry made with care and conscience.

The ring’s gentle curves and modest height make it ideal for those who favor understated elegance, whether worn alone or stacked alongside a wedding band. Its adaptable design suits a variety of hand shapes, especially those who appreciate a balance of presence and subtlety.
