Stone

Stone is a block found underground in the Overworld or on the surface of mountains.

Obtaining
Stone can be mined using a pickaxe, in which case it drops cobblestone. When mined without a pickaxe, it drops nothing. If a stone is mined with a Silk Touch enchanted pickaxe, it drops itself.

Natural generation
Stone makes up the majority of the solid blocks generated in the Overworld above y=0. From y=8 downwards, stone gradually transitions into deepslate, until it is completely replaced by deepslate at and below y=0.

When chunks generate, stone can be found under 1-5 layers of grass blocks, dirt, gravel, clay, coarse dirt, podzol, mycelium, sand, sandstone, red sand, red sandstone or terracotta, depending on the biome.

When the world is generating new chunks, some stone is replaced with blobs of other blocks. They may also be revealed on the side of small hills.

Stone also generates in igloo basements and some Overworld ruined portals.

Stone also makes up most of the blocks on the void start platform, in Superflat worlds created with the Void biome preset.

Post-generation


Stone can also be made by lava flowing on top of water blocks (both flowing and source). The water is replaced by stone.

Smelting
Stone can be smelted from cobblestone.

Silverfish
Silverfish can enter and hide in stone, creating an infested block.

Trading
Apprentice-level stone mason villagers offer to buy 20 stone for an emerald.

Note Blocks
Stone can be placed under note blocks to produce "bass drum" sounds.
