The diamonds in Minecraft are generated between Y -64 and Y 16, and the optimal layer is around Y -58 / Y -59.
It's right there, just above the bedrock, that the diamond ore has appeared more frequently since the version 1.18.

Where can I find diamonds on Minecraft?
the diamond ore appears between Y 16 and Y -64, and becomes increasingly dense as you dig down toward the bedrock. It's no coincidence that diamond remains the most coveted resource.
Your diamond tools and armor offer far superior strength and durability compared to the iron. And most importantly, you need diamonds to get the equipment in Netherite, the most powerful one in the game.

The best layer for finding diamonds, depending on your version
Since the update 1.18, ore production has remained virtually unchanged. Diamond production is divided among Y 16 and Y -64, with a density that increases as you get closer to the bedrock. In practice, aim for Y-58 or Y-59 no matter what version you're using.
| Version | Optimal layer |
|---|---|
| Minecraft 1.18 to 1.21 | Y -59 (make a small indentation at Y -58 to rest your feet) |
To find out your exact location, tap F3. The value Y The displayed reading shows your depth.
Tips and tricks for finding diamonds
How do I find out my Y coordinates in Minecraft?
Press the key F3 on your keyboard: coordinates appear on the screen. Your Y level is read on the line XYZ, highlighted in red in the illustration below.

It is this Y value that tells you your depth layer. Go down to Y -58 (Where -59) to put you where the diamond ore is the densest.
Key places to find diamonds in Minecraft
Contrary to what is often written about the Minecraft ores, not all caves are created equal when it comes to diamonds.
Note: Diamond is the only ore subject to the «reduction by exposure to air» rule. A block exposed to air is less likely to yield diamond ore, which makes traditional caves less profitable than one might think.
Two exceptions to be aware of:
- The flooded caves and ravines : The rule does not apply to water; the rate remains normal for water.
- The abandoned mines and large, deep caverns, useful early in the game because they quickly expose a large area.
In the long run, tunnel mining at Y-58 remains the most cost-effective method.
To explore the flooded areas without wasting any time, you'll need a water breathing potion. The recipe is detailed in our dedicated article.
What equipment should you gather before mining diamonds?
Before going downstairs, gather the Essential equipment To mine in Survival mode:
- A iron pickaxe at the very least, because a stone pickaxe doesn't harvest anything from the diamond ore.
- A bucket of water To neutralize the lava: the source blocks turn into obsidian, and the flowing lava turns into stone.
- A shovel to clear away the dirt and debris.
- Regarding the torches to light your way and keep monsters from appearing.
- A iron armor to withstand the impact during mining.
- Regarding the coffers to store the gems you've collected.
Once you've earned your first diamonds, you can move on to diamond tools. Also check out How to Make an Axe in Minecraft to round out your gear.
Optimized mining techniques for finding diamonds
A good optimized mining saves you a lot of time. Two reliable techniques keep coming up in the community:

- Move in a straight line to cover as much ground as possible.
- This method prevents you from falling directly into a lava lake.
2. Staircase mining
- Go down the stairs to reach the lower levels without a drop.
- Never mine the block right under your feet to avoid falling into the washer.
- Keep your bucket of water Grab it as soon as you come across a vein surrounded by lava.

I really liked it because I'm terrible at mining and I'm very unlucky, so if it maximizes my chances of finding diamonds, then I'll take it 🙂
I wonder if there is a similar article for old debris. I hope so!
