Lab-Grown Diamond Engagement Ring

When light catches the gentle curves of a heart-shaped diamond, it whispers a quiet promise—intimate, unmistakable. This semi-set solitaire invites you to choose a 9 x 9 mm center stone, its tender silhouette poised to become the centerpiece of your story.

Crafted in warm 10K rose gold, the band’s subtle glow complements the diamond’s romantic form, while the low-profile setting ensures a graceful wear that slips easily beneath a glove or alongside other rings. Each piece is meticulously finished by hand in our Williamsburg studio, polished to a soft sheen that feels as natural as a second skin.

Our diamonds are lab-grown, offering clarity and brilliance with a mindful footprint—reflecting a commitment to ethical jewelry without compromise.

This solitaire suits those who cherish understated elegance and a design that balances bold symbolism with everyday comfort. Its slender band and secure prongs make it ideal for stacking or wearing solo, adapting seamlessly to your lifestyle.

Should you need resizing or prefer a custom fit, our Brooklyn studio offers personalized consultations to ensure your ring feels uniquely yours.
