Diamond

Diamonds are the gems that are dropped when diamond ore is mined. Diamond is considered one of the most valuable items in the game due to their scarcity and use as a crafting material. Diamond can usually be found around 7 to 10 blocks above bedrock. Diamond tools and armor can be made from it, and are the most durable and efficient in the game. Diamonds can also be used to make jukeboxes, enchantment tables and solid diamond blocks. Diamond pickaxes are the only pickaxes that can be used to mine obsidian.

Diamond ore can be found in layers 1-16, in small veins of 1-10 ores, and can only be mined using an iron or diamond pickaxe. Outside of mining, diamonds can be rarely found in naturally generated chests, such as those found in a village or an abandoned mine shaft.

Diamond is the second rarest mineral in the game. The rarest is emerald ore. The texture is also one of the many symbols and icons used for Minecraft today.

Where to look for Diamonds
Don't look for Diamonds. They are not as good as iron. Get three diamonds, and never worry about them. They are as useless as dirt, unless you want to go to the worthless nether. Iron all the way, bro. -Ali

Smelting
 *  Ore can only be obtained by using the "Silk Touch" enchantment, by using inventory editors, or in creative mode.

As a crafting ingredient
In the Pocket Edition, the Nether Reactor Core is crafted with three diamonds and six iron ingots.

Trivia

 * Diamond tools and armor are actually renewable since they can be bought from Villagers. However, diamonds themselves remain nonrenewable.
