Lab-Grown Diamond Engagement Ring

Light catches the elongated curves of a marquise diamond, casting a slender, graceful shadow that seems to dance with every movement. This semi-set solitaire invites you to choose a center stone that will become a personal emblem of your story.

Crafted in warm 18K rose gold, the mounting’s delicate prongs cradle the stone with precision, while the smooth white gold band offers a subtle contrast and a refined silhouette. The low-profile setting ensures the ring rests comfortably for daily wear, its polished finish reflecting the Brooklyn studio’s meticulous handwork.

Each lab-grown diamond option embodies clarity and brilliance without compromise, reflecting a commitment to sustainable luxury that quietly honors the earth.

Designed for those who appreciate a slender, elegant shape, this marquise solitaire complements slender fingers and elongates the hand. Its streamlined form pairs effortlessly with stacking bands or stands alone as a statement of quiet confidence.

Should you wish to adjust the fit, resizing is handled expertly in-studio to maintain the ring’s seamless balance.
