Andesite

"Andesite is one of the three special stone variants that you'll find in Minecraft, alongside granite and diorite. All three were added at the same time in snapshot 14w02a back in 2014. They generate in place of stone underground below y-level 80, in veins of similar shape and size to gravel and dirt, but as well as looking underground, you'll occasionally find andesite exposed to the surface in extreme hills biomes. Igloo basements and woodland mansions have a few blocks too."

- Duncan Geere

Andesite is a type of igneous rock.

Polished andesite is the polished version of andesite.

Natural generation
One block of polished andesite can be found in igloo basements. Polished andesite can also be found in the "nature", "blacksmith", and "large jail" rooms of woodland mansions.

Andesite generates naturally in coral reefs, replacing some coral as part of coral crusts.

Andesite can generate in the Overworld in the form of mineral veins. Andesite attempts to generate 10 times per chunk in veins of size 1-33, from levels 0 to 79, in all biomes.

Breaking
Andesite can be mined using any pickaxe. If mined without a pickaxe, it drops nothing.

Trading
Journeyman-level stone mason villagers have a $1/3$ chance to sell 4 polished andesite for one emerald as part of their trades.

Apprentice-level stone mason villagers have a 25% chance to sell 4 polished andesite for one emerald as part of their trades.

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

Trading
Journeyman-level stone mason villagers have a $1/3$ chance to buy 16 andesite for an emerald.

Trivia

 * In real life, andesite is an extrusive igneous rock, meaning that it is formed from magma (thus igneous) that had flowed out to the surface (thus extrusive) as lava and cooled down.
 * Andesite's intrusive counterpart is diorite, meaning that diorite and andesite are made of the same materials but diorite formed inside the earth instead of flowing out.
 * In other words, andesite is rock formed from cooled lava, and diorite is rock formed from cooled magma.
