Diorite is a type of igneous rock.

Polished diorite is the polished version of diorite.

Natural generation
Diorite generates in coral reefs, replacing some blocks of coral crust.‌ [Bedrock Edition only]

Polished diorite also generate in warm underwater ruins.

Diorite generates in weaponsmith houses, tannery houses, and mason houses in snowy tundra villages.

Mineral veins[edit]
Diorite can generate in the Overworld in the form of mineral veins. Diorite attempts to generate 10 times per chunk in veins of size 33, from altitudes 0 to 80, in all biomes.

Trading[edit]
Apprentice-level stone mason villagers have a 1⁄4 chance to sell 4 polished diorite for an emerald as part of their trades.‌ [Bedrock Edition only]

Journeyman-level stone mason villagers have a 1⁄3 chance to sell 4 polished diorite for an emerald.‌ [Java Edition only]

Usage

Trivia

 * In real life, diorite is an intrusive igneous rock, meaning that it is formed from magma (thus igneous) that has cooled and turned into the rock below the surface of the earth (thus intrusive).
 * Diorite's extrusive equivalent is andesite, meaning that andesite and diorite are made of the same minerals, but andesite rocks are formed outside the earth instead.
 * In other words, diorite is rock formed from cooled magma, and andesite is rock formed from cooled lava.
 * Diorite is composed mainly of feldspar and small amounts of quartz and other minerals. It is an extremely hard rock and difficult to carve and work with.
 * In Minecraft: Story Mode, Reuben's grave on Episode 4 is made out of diorite and a new stair variant of it which cannot be found in Minecraft until the Village & Pillage update, which was announced months after Episode 4. It is unknown whether diorite slabs are present or not.
