About

MHART is a New York–based jewelry brand handcrafted by designer Michael Hartney. Since 2010, every piece has been individually made by hand, using natural gemstones sourced from the earth and caged in finely-woven silver or gold chain — a design signature inspired by the geometry and strength of a spider web.

Each gemstone is one-of-a-kind — no repeats, no stock stones. Every design reflects Michael’s obsessive attention to detail, built with both precision and intention. MHART jewelry isn’t mass-produced. It’s engineered, shaped, and assembled by one set of hands — start to finish.

Our guiding pillars:

One-of-a-kind-designs: Wear a piece of jewelry that no one else has. Each gemstone is ethically sourced and intricately caged in silver or gold chain designed to mimic a spider web surrounding each gemstone. The webbing is both elegant and eye-catching. The gemstones themselves are each unique, with their own colors, patterns, and shapes. No two are alike, making each piece of jewelry truly one-of-a-kind.

Our Mission: We want to make our planet a better place. MHART plants a tree or removes one piece of plastic from the ocean for every website purchase. Learn more about our sustainability efforts.
