No Diamonds

This mod removes all diamonds from Minecraft, so you can’t mine them, find them, or use diamond gear. It makes mid-game and late-game progression way tougher.

About this Mod

No Diamonds completely deletes diamond ore, diamond drops, and all diamond-based crafting. You can’t get diamond tools, armor, weapons, or enchantment tables. Loot chests won’t generate diamonds, villagers won’t trade them, and mining won’t uncover any. This forces players to rely on iron or jump straight to netherite (if allowed), making survival harder, bosses stronger, and progression way slower. It turns the game into a more hardcore, grind-heavy experience where you have to adapt without one of Minecraft’s most important resources.
