A diamond pickaxe is a tool crafted from sticks and diamonds, making it one of the most durable and efficient pickaxes in Minecraft. It is the lowest tier pickaxe capable of mining obsidian, which is required to access the Nether. With high durability and fast mining speed, a diamond pickaxe is commonly used for long-term mining and enchantments. Due to the rarity of diamonds, it is often obtained later in the game and can be upgraded to a netherite pickaxe for even greater durability.
