Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a 4 x 4 mm square diamond, its facets reflecting a quiet brilliance that feels both modern and intimate. This semi-set solitaire ring offers a refined foundation, inviting you to select a center stone that speaks to your story.

Crafted from warm 18K rose gold, the band’s gentle curve contrasts with the crisp geometry of the square setting, creating a subtle dialogue between softness and structure. The low-profile mounting ensures the ring sits comfortably for daily wear, while the polished finish highlights the metal’s natural glow.

Each piece is thoughtfully designed in our Williamsburg studio, where lab-grown diamonds are chosen for their clarity and ethical origin, minimizing environmental impact without compromising on sparkle.

Ideal for those who appreciate clean lines and understated elegance, this solitaire base pairs effortlessly with stacking bands or stands alone as a statement of refined taste. Its balanced proportions suit a variety of hand shapes, offering a comfortable fit that feels natural and secure.

Should you wish to adjust sizing, our in-studio experts provide careful resizing to maintain the integrity of the design. Typical lead times allow for personalized consultation and finishing touches.
