Michael transforms one-of-a-kind gemstones into wearable pieces of art that dare you to embrace your individuality.
Each piece is built around the natural shape of the gemstone—never forced, never symmetrical by design. The chain responds intuitively, wrapping organically to form a sculptural, architectural shell. Each link works in tension, creating a flexible yet supportive cage that balances force and form, delicacy and strength. The result is a one-of-a-kind design shaped by the stone.
At MHART, we believe that jewelry is more than adornment—it’s a statement of individuality. Nestled in the heart of NoLita at 5 Kenmare Street, our studio & retail space in New York City invites you to explore a world where bold silhouettes, rare stones, and sustainable craftsmanship converge.
Founded by designer Michael Hartney, MHART jewelry is handmade in our studio beneath the shop, featuring one-of-a-kind gemstones and thoughtfully designed metalwork.
