Diamonds are one of the hardest items to find in the game and are used to create the most power and durable items. The first tip to finding Diamonds is that they will only spawn in the bottom 17 layers of the Overworld. The easiest way to get to this level is to create a path directly down to the bottom layer,This should be done like a staircase so you can efficiently go down at a fast pace and also be able to get back out of the mine. The bottom layer of the map is actually layer 4. This means the layers 13 or so above this is where you can find Diamonds. They spawn in batches of between 2-8 blocks so if you find one dig around more to find at least one more. The player is able to now just dig in any direction to try and find Diamonds.
A different method is to try and find caves or mineshaft that were generated with the map. Since caves and mineshaft areas have already been dug out you can see a vast amount of blocks that may be Diamonds. Now that you have learned how to find Diamonds in Minecraft, it can be used to create Pickaxes, Swords, Axes, and more!
