Lab-Grown Diamond Engagement Ring

When light catches the gentle curves of a heart-shaped diamond, it whispers a quiet promise. This semi-set engagement ring offers a delicate 5 x 5 mm heart silhouette, poised to become the centerpiece of your own story.

Crafted in warm 18K yellow gold, the band is designed for everyday grace—smooth to the touch with a subtle five-stone setting that balances sparkle and wearability. Each prong is meticulously finished by hand in our Williamsburg studio, ensuring a secure yet low-profile embrace for your chosen center stone.

Our commitment to lab-grown diamonds means your ring carries clarity and brilliance without compromise, reflecting a thoughtful approach to ethical jewelry.

The slender band suits a variety of hand shapes and sizes, offering a comfortable fit that pairs beautifully with stacking rings or worn solo. Its modest profile slips easily beneath gloves or sleeves, making it a versatile choice for daily life.

Should you need resizing, our Brooklyn studio provides attentive adjustments to ensure your ring fits just right.
