Lab-Grown Diamond Engagement Ring

When sunlight catches the gentle curve of a 3.2 mm round diamond, it sparks a quiet brilliance that feels both intimate and enduring. This semi-set solitaire ring invites you to choose a center stone that will become the heart of your story.

Crafted in warm 14K rose gold with a polished white gold band, the setting balances softness and modernity. The low-profile mounting ensures the ring sits comfortably against the finger, while the smooth finish and subtle tapering offer ease for daily wear. Each piece is meticulously hand-finished in our Williamsburg studio, where precision meets quiet artistry.

Our diamonds are lab-grown, offering clarity and sparkle with a mindful approach to sustainability. This ring’s design suits those who appreciate understated elegance—its slender band pairs effortlessly with stacking rings or stands alone as a refined statement.

Because the center stone is selected separately, you can tailor the diamond’s size and quality to your preference. Resizing is available to ensure a perfect fit, crafted with care to maintain the ring’s seamless silhouette.
