Deepslate

Deepslate is a stone type found deep underground in the Overworld that functions similarly to regular stone, but is significantly more difficult to break.

Breaking
Deepslate can only be obtained by mining it using a pickaxe with the Silk Touch enchantment, otherwise it drops cobbled deepslate. If broken with any other tool, it drops nothing. The breaking time for deepslate is twice the time for stone.

Natural generation
Deepslate makes up the majority of the solid blocks generated below Y=0 in the Overworld. Stone is gradually replaced from Y=8 to Y=0 until it is completely replaced by deepslate.

Deepslate also generates in ancient cities.

Chest loot
On, they generate a furnace with 24 deepslate inside of it.

Smelting
Deepslate can be smelted from cobbled deepslate.

Usage
Deepslate can be placed in three orientations, similarly to logs. Silverfish can enter and hide in deepslate, creating an infested block.

Note blocks
Deepslate can be placed under note blocks to produce the "bass drum" sound.

Trivia

 * According to Brandon Pearce, the reason for changing the name "grimstone" to "deepslate" was because the word "grim" had too many connotations related to a negative feeling and therefore did not accurately describe the block as to what it actually was. The name "deepslate" was eventually chosen because of its location within the world and to more accurately represent that it is a type of slate.
 * Similar to stone, the orientation of the texture varies depending on the coordinates.
