Deepslate

Deepslate is a stone type found deep underground in the Overworld that functions similar to regular stone but harder than the stone.

Breaking
Deepslate can be obtained only 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 roughly twice the time for stone.

Natural generation
Deepslate generates in the Overworld in patches, attempting to generate 10 times per chunk in blobs of size 0-160, from elevations -4 to 16. All ores that generate replacing deepslate or tuff become their deepslate type.

Deepslate is found below Y=0 (in negative layers, replacing stone) if the Caves and Cliffs is applied to a world or the Caves and Cliffs Experimental Gameplay toggle is turned on.

Smelting
Deepslate can be smelted from cobbled deepslate.

Usage
Deepslate can be used as a decorative block. Silverfish can enter and hide in deepslate, creating an infested block.

Cobbled deepslate
Deepslate can be mined using a pickaxe without the Silk Touch enchantment to obtain cobbled deepslate.

Note Blocks
Deepslate can be placed under note blocks to produce "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.
