Rubble stones and blocks

Rubble stone refers to pieces of limestone that are relatively small (generally, they can be handled by hand). They can be completely rough (not cut), partially cut, or square (six surfaces more or less roughly cut). Blocks, on the other hand, are parallelepipedal elements that are usually a few sizes larger and can have different degrees of finish. Blocks and rubble stones usually come free during the demolition of walls and are often reused as such.
