Lab-Grown Diamond Engagement Ring

When light catches the delicate curves of a heart-shaped diamond, it whispers a quiet promise—one of intimacy and enduring affection. This semi-set solitaire invites you to choose a 10 x 10 mm center stone that will become the unmistakable heart of your story.

Crafted in warm 10K rose gold, the band’s gentle glow complements the diamond’s romantic silhouette, while the low-profile setting ensures a comfortable fit for daily wear. Each ring is meticulously finished by hand in our Williamsburg studio, where precision meets quiet artistry.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both beauty and sustainability without compromise.

The slender band suits those who favor understated elegance and pairs effortlessly with wedding bands or stackable rings. Its smooth contour feels natural beneath gloves or alongside other jewelry, designed for life’s intimate moments and everyday grace.

Should you wish to adjust the fit, resizing is available to ensure your ring feels as personal as the promise it represents.
