Diamond Ore

Diamond Ore is a type of ore that drops a diamond when mined. Diamonds can be used to craft tools and armor of the highest power and durability. Diamond Ore is most commonly found in layers 0-16 above bedrock. Diamond Ore is the second rarest ore in the game, after Emerald Ore if you have the right biome!

Obtaining
To obtain diamonds, the ore has to be mined using an Iron Pickaxe or above. The ore block will drop a diamond, but when the player uses an Fortune Pickaxe on it, its drops are increased, depending on the level of the enchantment used on it.

Trivia

 * Diamond Ore is much more easily found in caves.
 * Earlier, Diamond Ore was second rarest to Lapis Lazuli but this was changed in Update 0.9.0 when Emerald Ore was added.
 * Mining diamond ores will drop Experience Orbs.
 * Since Update 0.12.1, players can use an Iron or Diamond Pickaxe that has the Silk Touch enchantment to mine the ore itself, making a good decoration block to be added to builds.
