Cobblestone

Cobblestone is a common block used for creating various items, that resembles an uneven, roughly paved surface. Cobblestone only occurs naturally in dungeons, NPC Villages, and strongholds. It is commonly used to create walls for constructions with a medieval appearance such as castles, towers and roads. Cobblestone is obtained by mining stone. Cobblestone is slightly harder to mine than normal stone, and there is an alternative version of the block known as Moss Stone. Silverfish have the ability to enter and hide in cobblestone.

Uses
Cobblestone is a basic building block required for the crafting of many essential tools and items.

Cobblestone is required to craft furnaces, Cobblestone Slabs, stone stairs, stone tools and weapons, levers, Pistons, dispensers and Brewing Stands. Because of its fair blast resistance, immunity to Enderman griefing, and the abundance of stone, cobblestone is a very commonly-used building material. Cobblestone can be smelted back into smooth stone in a furnace.

Stone tools are easy to craft and widely available early in the game, making them very efficient even when iron is accessible. However, they possess the lowest enchantability of all tool sets, surpassed even by wooden tools.
