Metamorphic rock can be coarse grained or fine grained.
A fractured surface--rough. A polished or worn surface--smooth.
Slate is a fine-grained metamorphic rock that is characterized by its ability to easily split into thin layers. It often has a smooth texture and is commonly used for roofing tiles, flooring, and countertops.
Slate is a common metamorphic rock that can be made into a chalkboard due to its ability to easily break into thin sheets and its smooth texture that allows for writing on with chalk.

Marble is the metamorphosed result of limestone. Therefore, marble is metamorphic.
Metamorphic rock can be coarse grained or fine grained.
Metamorphic rocks can have a range of textures, from smooth to rough, depending on the minerals present and the intensity of the metamorphic processes they underwent. Some metamorphic rocks, like gneiss, can have a rough texture due to the presence of minerals like quartz and feldspar.

The Taj Mahal is made out of smooth, white marble which is a metamorphic rock.
Dolerite is very rough.
Metamorphic rocks generally are not categorized by their roughness, but instead by their degree of foliation or lack of it. The "roughness" of a metamorphic rock is unknown unless sample is in hand.
Gneiss is a coarse-grained metamorphic rock that can have a range of textures and appearances. While some gneisses can have a shiny appearance due to the presence of minerals like mica, they are generally not smooth like polished stones but rather have a rough or bumpy texture due to their mineral composition and formation process.

igneous is black and smooth metamorphic is magnetic and sedimentary is used as cement
metamorphic rock is made by heat and pressure on layers of sediments and in creates a smooth rock such as granite.
