However, there are a few tricks that could help you find diamonds a lot faster. First it’s important to know where and how diamond ores are spawned when the world is created. Diamond ore can only be found in the bottom 17 layers of minecraft diamond ore Overworld in small chunks of 2-8 ores.
However, it’s not uncommon to find just a single diamond ore, this happens when a cave, dungeons or other land mark is created over the other diamond ores that were attached to it. By keeping this in mind, creating efficient mineshafts becomes very easy, though it could take a while before you find diamonds, which is only to be expected of such a rare block. Digging down The first thing you want to do is dig down to layer about layer 13, you can tell you’re on layer 13 by pressing F3 in game. A lot of different information will appear on your HUD, but we want the coordinates in the left top corner. The Z coordinate indicates height, so it has to be 13. You could also count upwards from the top layer of bedrock you can find, which is layer 4.
Layer 13 will be where we start out first mineshaft branch. You can also start on layer 14 or 12, it doesn’t matter too much as, we’ll only dig on 3 different levels. Creating the mineshafts To start out mineshafts, first dig in 1 straight line for as far as you want, it doesn’t matter how far you go, it’s really depends on how much time you have and on how many pickaxes you’ve brought with you. 2-3 blocks deep, in each side of this main tunnel. However, make sure you leave 3 blocks between each tunnel on the same side. Continue to do this until you’ve reached the end of the main tunnel again.
