What is the best level to find diamonds in 1.20?

In the 1.20 version of Minecraft, the best level to find diamonds is between Y=5 and Y=12. These are the optimal levels for finding diamonds as they are most commonly found in this range. Diamond ore spawns in veins of 1-10 blocks at these levels, with most veins having around 3-7 blocks.

Players can increase their chances of finding diamonds by mining in caves or tunnels at these levels, as well as using tools such as enchanted pickaxes with Fortune enchantments. Additionally, mining in a straight line or branch mining can also help increase the chances of coming across diamond ore.

It is important to keep in mind that diamond ore is quite rare and may take some time to find, so patience and persistence are key when searching for diamonds in Minecraft.
