Diorite

Diorite is a type of igneous rock.

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

World Generation
Regular diorite 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 commonly in other biomes.

Usage
Diorite is currently only used for decoration. It has the same blast resistance as stone, meaning it can be used as a substitute for stone when building.

Video
Note: The video states that diorite and polished diorite can be used to craft stone slabs. This is incorrect.

Trivia

 * In real life, diorite is an intrusive igneous rock composed mainly of feldspar and small amounts of quartz and other minerals. It is an extremely hard rock and difficult to carve grand work with. Its extrusive equivalent is andesite.
