Busiest heights
Y=−59 / −58
Deepslate diamond ore shows up most often here, according to the wiki.
Old habit
Y=11
Classic pre–Caves & Cliffs habit. Wrong for modern worlds.
This is where diamond ore is supposed to spawn in a modern Overworld, from the public wiki tables. For counted ore in real chunks, see my 1,024-chunk Java dig.
Digging at Y=11 in a new world wastes time. The busiest diamond heights now sit in deep deepslate.
Y=11 is the old neighborhood, and diamonds live much lower now
You open the debug screen (F3) and watch the height number, called Y. An old video told you to dig at Y=11. You branch out through stone, and the diamonds do not show.
That advice is leftover from before the world got deeper. In a modern world, diamond ore lives much lower, in deepslate, the dark stone near the bottom. The public wiki says the busiest heights are about Y=−58 and Y=−59.
That is a long drop from the old habit. Y=11 is still ordinary stone. The busiest spots now sit in deepslate, about 70 blocks lower.
Where players aim vs the old myth
Illustration only. Relative bars (20 vs 100), not counted ore per chunk. Those heights come from the wiki, not my Java count.
| Label | Value |
|---|---|
| Old habit Y=11 | 20 |
| Modern Y=−59/−58 | 100 |
Where to dig in Survival
A common habit matches the deepslate heights: strip or branch around Y=−59 to −54. Use an iron pick or better. Light the tunnel. Watch for lava.
Fortune multiplies how many diamonds drop when you break the ore. It does not change where the ore spawns.
Skip Y=11 in modern worlds. Aim for deep deepslate around Y=−58 / −59, or a short tunnel about −59 to −54.
How I calculated it
These heights come from the public wiki tables, not from counting ore in a world. Minecraft Wiki Diamond Ore, natural-generation section (saved 2026-08-12). The wiki says diamond shows up most often at Y=−58 and Y=−59. I also point to a measured Java count of 1,024 chunks (I counted diamonds in 1,024 chunks), so this is not wiki-only.
The wiki lists four Overworld batches:
Source: Minecraft Wiki. Diamond Ore · Natural generation (pull 2026-08-12). Skips when next to air make caves look stingier than flooded caves.
| Batch | Y range | If it touches open air |
|---|---|---|
| 7 blobs of 1–5 / chunk | Y=16 → −63 | 50% skip if next to air |
| 1 blob of 1–23 every 1/9 chunks | Y=16 → −63 | 70% skip if next to air |
| 4 blobs of 1–10 / chunk | Y=16 → −63 | Never if next to air |
| 2 blobs of 1–10 / chunk | Y=−4 → −63 | 50% skip if next to air |
Numbers come from the wiki’s Diamond Ore page as of 2026-08-12. Experimental worldgen or a future rewrite can nudge those heights. Pin the answer to your version. This FAQ does not recount ore in fresh chunks. The companion Java count does.
