Slate

Slate is a metamorphic type rock with a layered structure, allowing it to be cleaved apart into thin sheets. This creates the unique surface texture that shows the natural ridges and layers of the stones structure. Quarried by prying apart layers of stone, the surface exposed is quite colorful, in some cases exposing minerals trapped between the layers of stone. slate are found in black, charcoal, cool greys, browns, rusty reds, green, copper or plum colors.
