If you're playing Minecraft 1.18 or later, you can go down below Y=0 and into negative figures. Below Y=0, you'll find all the usual ores, including Diamonds, embedded in Deepslate blocks instead of regular Stone blocks.
As we said, to find diamonds in Minecraft 1.19, you need to go down to a level from Y= 15 to Y= -63, and Y=-59 became the best level for mining diamonds. In addition, diamond mining is more difficult in the new version.
Diamond used to appear between Y=0 and Y=15 with most generated between levels one and five. While the ore still starts generating at 15, it now becomes more and more common as you dig deeper into the earth. Diamond has the highest odds of spawning at Y=-64.
I decided to do some strip mining under the ocean floor at level 11. It took me a very very long time to find diamonds, like a couple of hours. I sailed to the neighboring mega taiga, mined at level 11 and found diamonds within 10 mins.
Fewer than 30% of diamond mines are underground. The diamond ore must be of relatively high value, because the cost of underground mining is considerably higher and the amount of ore recovered is considerably lower. Some mines in South Africa reach depths of over 4 kilometers.
The vast majority of diamonds form between about 150 to 200 km below Earth's surface. But a handful come from much deeper.
The best Y Level to find Diamonds in Minecraft 1.19 and newer is Y=-59. It should be noted that you'll need a Pickaxe of Iron-quality or higher to mine the Diamonds you encounter. We'd also recommend trying to get the Fortune enchantment on your Pickaxe so you can acquire even more Diamonds when mining the ore.
The best method for mining Diamonds in Minecraft 1.19 is to dig down to level -57 and dig a long 2-block-tall tunnel in any direction. Then start to mine out to either side in more 2x1 tunnels, leaving a 2-block-wide gap between each new tunnel.
Following the Cave Update in Minecraft, the best level for Diamonds is approximately anywhere below Y:-58. The reason -59 is mentioned is that the player character stands two blocks tall, meaning the block level from the "waistline" and below would be Y:-58. The levels above Y:-58 at Y:-57 and...
Every Minecraft world is divided into layers — think of it like altitude. Sea level in Minecraft is roughly layer 64, for instance. The world goes down to layer -64. Diamonds only spawn at layer 15 and lower, and get more common the deeper you go.
Diamonds can be found anywhere beneath layer 16, but is most common in layers 5-12 in version 1.17. 1 and below; in versions 1.18 and later they are expected to be most common between layers -50 to -64. Most players find it through caving or mining.
Y level 11 will still technically work for diamonds, but that's a pretty rare find. Diamond ore can begin spawning at level 15. That's the highest they can be found in ore form.
Diamond ore veins can generate at most 10 diamond ores adjacent to each other. However, due to the ability of ore veins colliding with each other, players will have an extremely rare chance of mining a diamond vein up to 12 diamonds.
The Best Y Levels for Diamond in Minecraft Bedrock 1.19
If you're lucky enough, Diamond Ores can be found at any Y level ranging from Y=14 to Y=-63, and the lower you go, the more chances you have to find them. Your best bet is to hang around Y=-53 and Y=-59 for reliable Diamond Ore mining.
Usually, Diamond is found under layer 12, but now if you get to these -Y levels, the odds of finding diamond significantly increase: -50, -64, -59, and -58. It's important to mention that bedrock now appears at Y level -60.
As of Minecraft 1.19, the world height reaches 320 blocks, and the bottommost point is at -64 blocks. So, if you know the preferable height for each ore, you can expect to find them within most chunks of the game at those particular world heights.
diamond, a mineral composed of pure carbon. It is the hardest naturally occurring substance known; it is also the most popular gemstone. Because of their extreme hardness, diamonds have a number of important industrial applications.
Dimonds in Australia
Australia's largest and most economic diamond deposit has been the Argyle Mine, in the East Kimberley region of Western Australia. It started production in the early 1980s and was, for some years, the world's largest diamond mine by volume.
Some 142 million carats of diamonds were estimated to have been produced from mines worldwide in 2019. Major producing countries include Australia, Canada, the Democratic Republic of Congo, Botswana, South Africa, and Russia. Worldwide reserves are estimated to be some 1.2 billion carats.
Diamonds are not typically found in coal mines. Diamonds are created deep below the Earth's mantle, in a region known as the lithospheric mantle, at depths of up to 100 miles (160 kilometres). Coal is a sedimentary rock and coal mines do not have the conditions necessary for diamond formation.
Diamond is only formed at high pressures. It is found in kimberlite, an ultrabasic volcanic rock formed very deep in the Earth's crust.
Combined with a dash of oceanic crust rock called eclogite, just over a quadrillion—a one with 15 zeroes—tons of diamonds are hiding within Earth, they estimate. To be fair, that's only a small percentage of the total rocks on Earth, Garber notes. By volume, around 2 percent of the cratonic roots are made of diamond.
