just need some so i can mine all of the diamonds that i have found! and i‘m struggling to find some iron so just looking for a rough area that i can find some :) 5* for the best answer!!
Just look on the side of a mountain. It is usually by Cole. If you can't do that then dig a little in a cave that should do the trick ;D
Iron is fairly easy to find, just go fairly deep into caves and you'll find them. BTW, in case you don't know, Iron is tan-ish color.
Usually I find them near mountains where the most stone can be seen. If you can find an unexplored Cave there is sure to be iron there.
