Where it belongs
Pyrite has weight and gleam — it holds a desk or a mantel with quiet authority. It rewards being picked up as much as looked at.
Formation
How it came to be
It forms in low-temperature sedimentary and hydrothermal environments, where iron and sulphur combine in the absence of oxygen.
Pyrite is iron sulphide, long nicknamed fool's gold for its metallic yellow lustre. Its natural tendency to grow in cubes makes it a favourite of collectors and crystallographers alike.
The mine at Navajún in La Rioja, Spain, is world-renowned for pyrite cubes of extraordinary sharpness, grown within a soft marl that is carefully removed to reveal them.
The cubes are not cut or shaped. Their flat faces and clean right angles are the direct expression of the mineral's internal atomic lattice.
The Object
We select clusters with bright, untarnished faces and well-defined cubes, keeping natural matrix where it lends context and stability.
Closer In
Under magnification the faces show fine striations running in alternating directions — the signature growth lines that distinguish natural pyrite from anything polished.
