Minecraft 1.18 is finally here, and that means it’s time to start exploring some deep caves and figuring out where the diamonds are with the new ore distribution. Luckily, the devs have provided some helpful charts and videos to get you pointed in the right direction.
Previously, most types of Minecraft ore would generate evenly regardless of the y coordinate, so if you were mining within a given ore’s height range, you had an equal chance of finding it. Now most ore has a sort of ‘triangular’ distribution pattern, meaning that you’re most likely to mine successfully toward the center of the height range.
As an example, diamonds generate in that triangular pattern between y-144 and y16. Since the Minecraft world ends at y-64, you won’t be able to reach those juicy diamonds spawning below the bedrock. That means, simply, that you’ll find more diamonds the deeper you go, as the lowest levels get you closest to the centre of the distribution pattern.
