Staircase method
The staircase method is the most ideal way to pave your way to the world’s depths efficiently and safely. The method involves doing exactly what the name suggests – start digging yourself down at an angle of 45 degrees such that you leave a staircase-pattern behind you. Dig one block deeper than the previous one with each step. This way, you can return to the surface by simply jumping your way up. The staircase covers plenty of ground and is a very common method of successfully finding diamonds.
Wander the caves
Exploring the cave systems is an effective way of finding diamonds on Minecraft. Some caves are jaw-droppingly massive, which gives plenty of visibility making it easier to spot Diamond Ore. If your way is filled with a lot of lava, a water bucket could really come in handy for creating easy paths.
Strip Mining
This method is rather dull. Strip mining involves literally mining everything for searching the rare ore. Begin by getting to the appropriate layer (1-16 for diamonds) and dig a box-shaped outline around yourself. This should leave you with a cube of blocks in the middle. Mine it and create an open area. You’ll ultimately find what you’re looking for, but it’s going to eat away a good chunk of your time. You’ll also end up with plenty of materials, particularly Cobblestone.
