Diamond

Diamonds are one of the rarest materials in Minecraft.

Natural generation
Desert temple, jungle temple, nether fortress, village blacksmith chests, and stronghold slab altar chests may contain diamonds in stacks of 1-3. Abandoned mineshaft chests may contain diamonds in stacks of 1-2.

Mining
Diamond ore mined using an iron or diamond pickaxe will drop a single diamond. If the pickaxe is enchanted with Fortune, it can drop an extra diamond per level of fortune, allowing for a maximum of 4 with Fortune III. If the ore is mined using a pickaxe enchanted with Silk Touch, it will drop itself rather than a diamond.

Usage
Diamonds are used to craft the most durable tier of tools and armor.

Trading
Villager armorers, tool smiths and weapon smiths buy 3-4 diamonds for one emerald as part of their third tier trades.

Trivia

 * Diamonds are a well-known item because they are one of the most shown things on merchandise.
 * In real life, diamond is very fragile in certain directions, so it is not a good material for tools or armor, except for cutting other materials.
