Hello. I am the person who makes skins. But Im not here to do that. im here t tell where and how good mineraft ores are. From Coal TO DIAMOND: I will tell you ow good they are and where to find them.

COAL: Coal can be found any level. Used for torches.

IRON: Found mostly in caves though you MAY find osme on hills. Used for medium tier tools and armour.

GOLD: Found at level 20 or lower. Used for clocks and tools, but tools have low durability,]

DIAMOND: Found at 16 or lower. Used to make high quality tools and armour. Can last for a long time. Also used fro: Jukebpxes, enchantment tables.

REDSTONE: used fro making games, contraptions. Cannot be made into tools, unless mods are involved.  Used to make many games. used in Cloxks, Compasees.. etc

EMERLAD: Found rarely in 30 or lower. Only in extreme hills, these gems can be found in veins of 1. They are used in trading.

I hope you enjoyed this little info about tiers. This is usually for newcomers.
