Best Y Level for Diamonds

About This Guide
Diamonds are the most important ore in early and mid game: tools, armor, enchanting tables, and jukeboxes all need them. Since the Caves & Cliffs update, diamonds generate from Y 16 down to the bottom of the world, with more of them the deeper you dig. Knowing the right height turns hours of random mining into a focused strip mine.
Best Y Level by Version
| Version | Best Y level | Diamond range |
|---|---|---|
| 1.18 and newer | Y -58 to -59 | Y 16 down to Y -64 |
| 1.17 and older | Y 5 to 12 | Y 1 to 16 |
Why Y -58?
- Diamond ore gets more common the lower you go.
- Below about Y -59, bedrock gets in the way.
- Lava lakes are common around Y -55 and below, so staying at -58 or -59 keeps your strip mine on solid deepslate most of the time.
Deepslate diamond ore is the same as regular diamond ore, just harder to mine.
How to Mine for Diamonds
- Dig a staircase down to Y -58. Never dig straight down.
- Strip mine: dig a 1×2 tunnel, then branch tunnels every 3 blocks.
- Use Fortune III on an iron or better pickaxe for more diamonds per ore.
- Bring a water bucket to turn lava into obsidian.
- Light your tunnels with torches so mobs don’t spawn.
Branch Mining vs Caving
| Method | Pros | Cons |
|---|---|---|
| Branch mining at Y -58 | Safe, steady results | Slow, lots of deepslate |
| Caving | Exposes lots of ore fast | Mobs, falls, and lava |
| Ancient cities | Diamond gear in chests | Sculk and the Warden |
Diamonds From Structures
Diamonds also show up in chests: buried treasure, shipwrecks, desert temples, jungle temples, villages, mineshafts, and end cities. Use the buried treasure finder or the desert temple finder for some easy extras.
Ores Near Diamonds
At Y -58 you’ll also find redstone, gold, lapis, and deepslate iron. See the full Minecraft ore distribution for every ore.

Frequently Asked Questions
What is the best Y level for diamonds in 1.21?
Around Y -58 to Y -59, the same as in 1.18 and 1.20.
Is Y -64 better for diamonds?
Diamonds are most common at the bottom, but bedrock fills the last few layers, so -58 is easier to mine.
Do I need Fortune for diamonds?
No, but Fortune III gives up to 4 diamonds per ore, which doubles your average.
Can I find diamonds with a seed map?
Ore positions come from the seed, but this site doesn’t map ores. Use the right Y level and a strip mine.
Final Thoughts
For diamonds, dig a staircase to Y -58, strip mine with branches every 3 blocks, and carry a water bucket. Add Fortune III and you’ll have a full diamond kit in no time.
