A Diamond Helmet is a durable piece of head armor crafted from diamonds, offering high protection and durability, second only to a netherite helmet. It is commonly used in mid-to-late game due to its strong defense against mobs and environmental hazards.

Diamond helmets can be enchanted with Protection, Unbreaking, and Respiration to further enhance their effectiveness. They can also be repaired using diamonds in an anvil or crafting table.

Due to its high durability and defensive capabilities, a Diamond Helmet is an essential piece of armor for players preparing for challenging fights, such as battling the Ender Dragon or Wither. It can also be upgraded to a netherite helmet for increased durability and knockback resistance.
