The Best Ore in the overworld is diamonds. A picture is displayed of the ore. This Ore does the most protection, damage, and durability in the Overworld.
The Worst Ore in the Game
The Worst Ore in the whole game is gold. All weapons with it have less durability as a wooden kind of it. The only good thing about it is that you can trade for items with piglens for it.
You will need iron to get any better ores. It is found in caves a lot. You get it from mining you can't mine it with a wooden pickaxe. If you have found a cave, be ready to fight some mobs.
