Minecraft Ore Finder
Enter your seed and a position to see every diamond ore vein (or ancient debris in the Nether) in the 3 × 3 chunks around you, with exact X Y Z. We tested it on the official Java 26.3 server: 94 % of the diamond blocks shown are real and it finds 95 % of all diamonds.
Checked in the real game: 94% of the diamond blocks we show are really there, and we find 95% of all diamonds (ancient debris: 92% / 97%). Some blocks near caves or water can be missing.
How to use the ore finder
Enter your seed
Type /seed in the game and paste it. Pick your Java version (1.18 or newer).
Enter your position
Use your X and Z from the debug screen (F3). The finder checks the 3 × 3 chunks around it.
Pick a vein
Veins are sorted by distance. The Y value is the lowest block of the vein.
Dig safely
Tunnel to the vein at its Y level instead of digging straight down, and carry water for lava.
How accurate is the ore finder?
We compared the finder with the real game on the official Java 26.3 server in 10 test worlds (90 chunks per ore):
| Ore | Blocks shown that are real | Real blocks the finder shows |
|---|---|---|
| Diamond ore | 94 % | 95 % |
| Ancient debris | 92 % | 97 % |
The finder reproduces the game's ore placement, including the terrain, noise caves, carver caves and the bedrock layer. It does not model aquifer water or blocks changed by other ores, so a few blocks next to water or gravel can be missing. The same test on 1.21.1 and 1.20.6 gave the same result.
Where are diamonds in Minecraft?
Diamond ore generates from Y 16 down to Y −64 and is most common at Y −58 to −59 (see our best Y level for diamonds guide). There are small veins, medium veins, rare large veins and "buried" veins that never touch air — which is why strip mining finds diamonds that caves hide.
Ancient debris is in the Nether between Y 8 and Y 119, most common around Y 15, and it never touches air.
Is using an ore finder cheating?
On your own singleplayer world it is your choice. Many servers do not allow seed-based tools — check the rules before using it on a server. On servers the world may also use a different seed or plugins that change ores.
Frequently asked questions
Does the ore finder work on Bedrock?
No. Bedrock places ores differently, so this finder is for Java Edition 1.18 and newer only.
Why is a diamond missing where the finder shows one?
About 6 % of the blocks we show are not there in the game, usually because the spot is next to water or another ore changed the rock first. Check the blocks around the vein.
Why does it only search 3 × 3 chunks?
Ore positions need the exact terrain around each vein, which takes time to calculate in your browser. Move your position to search other areas.
Can it find other ores?
Right now it finds diamond ore and ancient debris, the two ores people search for most. More ores may follow.
