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
Diamond can usually be found around 7 to 14 blocks above bedrock, though it can also be commonly found just a few blocks above bedrock. The best strategy to find diamonds, is to use the branch mining method. The reason why branch mining is the best way to look for diamonds, is because it exposes the most surface area, and is the method that requires the least amount of mining. You would want to be capable of seeing as many blocks as you can. There is a very good advantage, since ores in Minecraft can be visible on all 6 faces. You would also want to find diamonds in the least amount time, that's why having sight of all blocks would save you time than mining every bock you see. To branch mine, first dig stairs. Make sure that you are about 12 blocks above bedrock (eye level). Next, make a 1 block wide, and two block tall tunnel. you should make the tunnel at least 20 blocks long. Now, for every 4-6 blocks on either side of the tunnel, dig another tunnel 20 blocks long, 2 blocks tall, and 1 block wide. Repeat this process, and it is guaranteed that you will at least find 5 diamonds.
