Charoite

Formally described in 1978—a relatively new mineral. Found only along the Chara River basin in Siberia. Nowhere else on Earth.

Formed when alkaline granite meets limestone under high-pressure metamorphic conditions. This combination does not recur in any other known location, confining the source to a single point. Not rare by accident—isolated by geological inevitability.

Discovered during the Soviet era, though the government initially withheld its existence. When Western mineralogists first examined a sample during the Cold War, it matched nothing in the existing record. A stone that defied classification before it even had a name.

The thing you've been putting off — you know which one it is. If that sentence produced a specific image in your mind, this stone is ready for you. It won't push you from behind. I chose it for the point at which the last step finally needs to hold. Facing what you've been avoiding takes more than willpower. Sometimes willpower needs a floor to stand on.
