Lab-Grown Diamond Engagement Ring

When light catches the delicate curves of a heart-shaped diamond, it reveals a quiet promise of devotion. This semi-set engagement ring foundation invites you to choose a 5 x 5 mm center stone that will rest within a halo setting, amplifying its gentle silhouette with a ring of finely crafted pavé diamonds.

Hand-forged from warm 18K yellow gold, the band is shaped for everyday wear—smooth beneath the finger with a subtle taper that balances presence and comfort. The halo setting is meticulously assembled in our Williamsburg studio, where each prong is polished to a soft gleam, ensuring the diamond sits low enough to slip easily under gloves or stack alongside a wedding band.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, offering clarity and brilliance with a reduced environmental footprint.

This ring suits those who appreciate romantic symbolism paired with artisan craftsmanship, especially for hands that favor a refined yet approachable profile. The semi-set design allows for a personalized selection of your ideal heart-shaped diamond, making the final piece uniquely yours.

Should you need resizing or guidance on selecting the perfect center stone, our Brooklyn studio offers a pressure-free consultation to tailor every detail.
