A darker patch that won't wipe off — often greasy-looking with a soft outline.

A faint ring left behind after a glass or bottle sits on the surface.

An orange or brown discoloration, often around metal objects left on the stone.

A fine line, often catching the light, that you can feel with a fingernail.

A line that runs through the stone, sometimes with a visible separation.

A missing piece of stone, usually at an edge or corner.

A white, powdery bloom on the surface — often outdoors or in damp areas.
