Lab-Grown Diamond Engagement Ring

When light catches the gentle curves of a 6 x 6 mm heart-shaped diamond, it reveals a quiet declaration of affection—intimate and unmistakable. This semi-set engagement ring invites you to select a center stone that embodies your unique story.

Crafted in 18K white gold, the mounting features delicate accent stones that enhance the heart’s silhouette without overpowering it. The low-profile setting ensures the ring sits comfortably for daily wear, while the smooth band offers a subtle weight and balance that feels natural on the finger.

Each piece is meticulously finished in our Williamsburg studio, where expert hands polish and inspect every facet to meet exacting standards. The choice of a lab-grown diamond center reflects a commitment to ethical sourcing and environmental mindfulness.

Designed for those who appreciate refined craftsmanship and understated elegance, this ring complements a variety of hand shapes and fits easily beneath gloves or sleeves. Its modest height and secure prongs make it a practical choice for everyday life.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio offers personalized consultations to ensure your ring fits seamlessly.
