Minecraft ores

If there is no guy named Herobrine in Minecraft pocket edition, then where do you find diamonds? Find a blue ore and make a diamond with coal and your ore! I am talking about ores. Ores are stone resources in Minecraft that can be found in caves or underground. You need stone, diamond iron, or gold  pickaxes to mine the stonelike resource. I tried mining an iron ore with a wooden pick but it didn't work. There are gold, diamond, emerald, iron,coal, etc. you need a furnace to make your ingot, so... Cool! I found  a rare golden ore!
