Deepslate
minecraft:deepslateDeepslate is the stone-type block that dominates the Overworld below Y=0, forming gradually as stone transitions into it between Y=8 and Y=0. It has higher hardness and blast resistance than stone, drops cobbled deepslate without Silk Touch, and serves as the base ingredient for many deep-stone building variants.
FAQ
How deep do I need to go to find deepslate?
Stone begins transitioning to deepslate around Y=8, and deepslate becomes the dominant block below Y=0.

Why does deepslate take longer to mine than stone?
Deepslate has a hardness of 3, roughly double that of stone, so it takes about twice as long to break with the same pickaxe.
