Ah, this age-old question continues to plague me. I remember typing those very words into Google years ago and being both astounded and disappointed by the results.
If you have any preconceived notion of easy or automatic diamond farming, I’m going to burst your bubble right now. There isn’t one. Mining for diamonds, on an unmodded world, must be done manually. There’s no Redstone contraption that can help you out here (let’s be honest, there probably is one, but neither you nor I have the skill or attention span to make it).
Instead, you’re going to have to put in some hard work while optimizing your efficiency. I’m here to teach you how to do just that.
The Best Way to Mine for Diamonds in Minecraft
The best and most reliable method you have for mining diamonds is to create your own mines. Ravines and cave systems can yield you a handful, but having a fully home-grown mine is more manageable, profitable, and safer.
Diamonds start spawning at level 16. To get the most out of your surroundings, you’re going to want to dig down to level 12. Once here, you start strip mining.
Don’t get excited. Strip mining is a boring and arduous task, so find some YouTube videos to stick on in the background.
Your central corridor can be whatever size you want. I like doing a 6×4, but you do you. Dig out that space as much as you want.
From here, you’re going to start digging straight lines, or strips, off of the main corridor. These strips are one block wide and two blocks tall. You’re going to leave two rows of blocks between each strip to maximize efficiency.
Other methods of doing this involved lying down and digging a 1×1 tunnel, but I’m starting you off on the OG methods of mining.
You decide on a length to mine each strip to and just keep digging. You’re going to find a fair few diamonds this way.
This is, by far, the quickest and easiest method to get diamonds in Minecraft.
You do have other options like looting villages and other mining methods, but none of them are nearly as efficient as strip mining.
