Polished Granite Slab is a polished granite variant of a slab. It does not generate naturally and must be crafted or obtained through stonecutting. Polished granite slabs can be mined with any pickaxe. If mined without a pickaxe, they drop nothing.

They can be crafted using polished granite or obtained through stonecutting. Polished granite slabs function like other slabs in terms of placement and collision. They can also be placed under note blocks to produce a bass drum sound.
