Coal to Diamond Compressor Mod adds a block called a coal compressor, which converts your coal to diamonds! Once crafted, you can place the coal compressor down and add a stack of coal to it. Lava is also required for fuel, and each bucket lasts 40 seconds. Each diamond requires a full stack of coal to pressurize into diamonds, and the process takes a total of 2 minutes. Don’t break this block while pressure is built up, or it will release it all in an explosion!
