what is the best level for diamonds

The best level to mine diamonds in Minecraft as of the latest versions (1.20 and 1.21) is around Y-level -59 for the highest diamond concentration. However, many players recommend mining at Y-level -53 to avoid the common lava lakes that appear at Y-level -54, which makes it safer while still having a good chance of finding diamonds. Diamond ore can be found anywhere below layer 16, but their abundance is richest near the bedrock layers around -59. Thus, the ideal mining range is between Y-level -53 and Y-level -59 to maximize diamond finds while minimizing lava hazards.
