Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a 3 x 3 mm square diamond, its facets unfolding like a quiet promise on a slender band. This semi-set solitaire invites you to choose a center stone that reflects your unique story, framed by an 18K rose gold band that warms the skin with a gentle glow.

Crafted in Williamsburg, the ring’s smooth, low-profile setting balances elegance with everyday ease, designed to sit comfortably beneath a sleeve or glove. The polished rose gold shank is finished by hand, ensuring a seamless surface that feels as intimate as it looks.

Each lab-grown diamond option offers clarity and brilliance without compromise, embodying a commitment to ethical jewelry that respects both people and planet.

Ideal for those who appreciate subtle romance and modern geometry, this solitaire’s square silhouette complements slender fingers and pairs effortlessly with stacking bands or a wedding ring.
