Brecciated Jasper

"Brecciated" is a geological term meaning "composed of angular fragments." A stone that was once shattered, then recemented by a different mineral. The evidence of fracture and repair is preserved directly as pattern.

Tectonic activity broke the jasper apart. Silica and iron oxide flowed into the cracks and solidified, binding the fragments back together. Because the original stone and the binding mineral differ in colour, a distinctive mosaic emerges.

A stone that broke and became whole again. Unbroken specimens lack this complexity of expression.

He's rebuilt a situation from rubble at least once with his own hands. That kind of person doesn't panic at the sight of disorder — the body remembers the sequence. Pull this apart, lay it out, reassemble. This stone belongs near someone who already has that procedure stored in muscle memory. Collapse isn't a catastrophe if you've done the repair before.
