Granite

Granite is a stone-like material.

Polished granite is the polished version of granite. As with diorite and andesite, it can be crafted from regular granite.

Naturally generated
Regular granite generates anywhere underground in rich seams, in an identical way to the other two stone types, as well as gravel and underground dirt. It is most commonly exposed to the surface in Extreme Hills biomes but can also be found regularly in other biomes.

Crafting
Polished granite can also be crafted from regular granite, see below.
