Quick answer: Lapis lazuli is most common at Y 0 and spawns from Y 64 down to Y −64. This Lapis Finder marks lapis ore from your seed on a visual map at 89% accuracy on Java 26.2 and 86% on Bedrock 1.26.30.
Lapis spawns in two overlapping ways: a band centred on Y 0 that thins out above and below it, plus a smaller amount that gets more common the deeper you go. The combined sweet spot is around Y 0, near where stone meets deepslate. The finder marks the chunks most likely to hold a vein.
The best Y level for lapis lazuli is Y 0. The main lapis batch peaks right around the stone/deepslate boundary, so branch mining between about Y −5 and Y 5 collects the most. You will find lapis at other depths too, just less often.
Bedrock uses the same Y range and Y 0 sweet spot as Java. The finder supports Bedrock 1.26.30; switch the edition and the accuracy badge updates to the Bedrock figure (86%).
| Ore | Best Y level | Spawn range | Java accuracy | Bedrock accuracy |
|---|---|---|---|---|
| Lapis Lazuli | Y 0 | Y 64 to −64 | 89% | 86% |
Accuracy is the share of marked hotspots that really contain the ore in your world, shown as a plain number.

The Ore Finder reproduces Minecraft's own ore-placement maths from your world seed, entirely in your browser. It runs the same ore-distribution and cave-carving steps the game uses, then marks the chunks where diamonds, netherite and other ores are most likely to be exposed. Nothing is uploaded – your seed never leaves your device.
Where an ore ends up depends on the exact terrain and caves Minecraft carves around it, and no in-browser tool can rebuild every block the game places. We reproduce that terrain very closely, so a hotspot marked with a high percentage really contains the ore in your world around 85–91% of the time. A few spots may have been carved away by a cave or shifted slightly, so treat the markers as very strong leads rather than a guarantee.
In the Overworld it finds diamond, iron, copper, gold, redstone, lapis lazuli and coal, and in the Nether it finds ancient debris (netherite). You search one ore at a time and can optionally limit the search to a specific Y level.
Diamonds get more common the deeper you dig, peaking around Y -59 in current versions (they generate between Y -64 and Y 16). The finder defaults to each ore's full spawn range, and you can tick 'limit to a specific Y level' to focus on the richest band – for diamonds, around Y -59 to -54.
It works on both Java and Bedrock Edition. On Java it covers modern versions, including 1.21 and the 26.x releases, which share the same ore-generation rules. Bedrock Edition is now supported as well – on 1.18 and newer it finds the Overworld ores (diamond, iron, copper, gold, redstone and lapis lazuli). The two editions use different world generators, so make sure you pick the edition your world was created in.
That is up to how you like to play. In single-player it is just a faster version of strip-mining for a diamond start. On multiplayer servers, check the rules first – some servers don't allow seed-based tools.
