How to Find Diamonds in Minecraft Bedrock
Diamonds haven't moved since the Caves & Cliffs update. If you're still mining at Y=12 because that's what worked in 2019, you're digging in the wrong place. The ore distribution system changed in 1.18 and has stayed the same through every version since. This guide covers exactly where to mine, how to mine, and what to bring.
Best Y-Level for Diamonds
Diamond ore generates between Y = -64 and Y = 16. The deeper you go, the more diamonds you'll find. Density peaks at the very bottom of the world.
Y = -59 is the optimal level for maximum diamond density. This is where most experienced players mine.
Y = -53 is the safer alternative. Lava lakes generate around Y = -54, so mining one level above that avoids most lava encounters while still being in a high-density zone. If you don't have fire resistance potions or find yourself dying to lava often, mine here instead.
Avoid going below Y = -60. Bedrock blocks start appearing and eat into the available mining space, making your tunnels less efficient.
How to Get to the Right Level
If you don't have coordinates enabled, turn them on first: pause → Settings → Game → Show Coordinates. The Y value is your altitude.
From the surface, dig a staircase down. Don't dig straight down (you know why). A staircase pattern, one block forward and one block down, gets you to Y = -59 safely. Alternatively, find a deep cave and follow it down, checking your Y coordinate as you go.
Mining Methods That Actually Work
Branch Mining (Strip Mining)
The most reliable method for consistent diamond finds.
- Dig down to Y = -59 (or -53 if you prefer safety)
- Create a main tunnel, 2 blocks tall, in any direction
- Every 3 blocks along the main tunnel, dig a branch tunnel to the left or right
- Each branch should be about 30-50 blocks long
- Return to the main tunnel and repeat
Why every 3 blocks? Diamond veins are 1-8 blocks in size. Spacing your branches 3 blocks apart ensures you won't miss any vein between tunnels. Some players space branches every 2 blocks for absolute coverage, but the extra effort only catches a small percentage of additional veins.
Caving
Exploring large caves at the right depth can be faster than branch mining, with one major caveat. Diamond ore that would generate exposed to air in a cave gets reduced by the game's generation algorithm. This means caves show fewer diamonds on their walls than you'd find by mining through solid stone at the same level.
That said, caves let you cover a lot of ground quickly and you'll find other ores along the way. If you find a deep cave system that reaches Y = -50 to -59, it's absolutely worth exploring. Just don't rely on caving alone if diamonds are your primary goal.
TNT Mining
If you have access to TNT or creeper farms, TNT mining is extremely efficient. Place TNT at Y = -59, light it, and it blasts open a huge area. Diamond ore drops as items when blown up by TNT (unlike some other blocks), so you don't lose anything. The main cost is gunpowder, which is easy to farm with a creeper farm.
Air Exposure Reduction: What It Means
This is the mechanic that most guides mention but don't explain well. When Minecraft generates the world, it places diamond ore according to the distribution curve. But then it runs a second check: if a diamond ore block would be exposed to air (meaning there's a cave or ravine next to it), there's a chance the game removes it.
This is why branch mining through solid deepslate finds more diamonds than exploring caves at the same level. The diamonds in solid rock never got removed. Cave diamonds did, at least some of them.
It also means that if you find a diamond vein on a cave wall, there might be more diamonds hidden behind it in the rock. Always mine a few extra blocks around any diamond vein you find.
What to Bring
Iron pickaxe or better. Diamond ore requires at least an iron pickaxe to drop diamonds. Stone and wood pickaxes will break the block but give you nothing.
Fortune III pickaxe. If you have one, use it. Fortune III turns a single diamond ore into up to 4 diamonds. Over a mining session, this roughly triples your yield. If you don't have Fortune yet, consider using Silk Touch to collect the ore blocks and mine them later once you do.
Water bucket. Non-negotiable at Y = -59. Lava pockets are everywhere. A water bucket instantly converts lava to obsidian and saves your life and your items.
Food with high saturation. Golden carrots or cooked steak. Mining burns through hunger, and you need consistent health regeneration in case of lava or mob encounters.
Torches. Deep caves and tunnels are pitch black. Hostile mobs spawn in the dark. Light up your tunnels as you go.
A spare pickaxe. Nothing worse than your only pickaxe breaking mid-session at Y = -59 with a full inventory of diamonds and no way to dig back up.
Common Myths
"Diamonds spawn near lava." No. Diamonds and lava just generate in the same depth range. Lava doesn't attract or cause diamond generation. Mining near lava is dangerous, not more productive.
"Certain biomes have more diamonds." No. Biome type doesn't affect diamond ore generation at all. The distribution is identical everywhere. Some biomes have larger cave systems that might expose more ore, but the generation rate is the same.
"Mining at Y = 11 or Y = 12 is still good." It was, before 1.18. Now it's one of the worst levels for diamonds. The distribution shifted dramatically downward. Y = 11 has a fraction of the diamond density that Y = -59 has.
Quick Numbers
For context on what to expect from a mining session at Y = -59 using branch mining:
- A typical 1-hour session yields roughly 20-40 diamonds without Fortune
- With Fortune III, that jumps to roughly 50-100 diamonds
- Diamond veins on Bedrock are 1-8 ore blocks per vein
- You'll also find plenty of redstone and lapis lazuli at this level, since they share similar depth ranges
These numbers vary based on how fast you mine and how lucky your chunk generation is, but they're a reasonable expectation.
Wrapping Up
Mine at Y = -59 for max density or Y = -53 to avoid lava. Use branch mining with tunnels every 3 blocks. Bring a Fortune III pickaxe and a water bucket. That's the formula. Diamond mining on Bedrock hasn't changed since 1.18, so this method will work for every current and future version until Mojang decides to overhaul ore generation again.
