[SOLVED] How do I make pickaxes act like iron pickaxes?

So in vanilla Minecraft, you cannot mine redstone, lapis, diamond, gold, and emerald ore with a stone or wooden pickaxe. You must mine it with an iron, gold, or diamond one.

So how can I make it so that my pickaxe acts like one of those, meaning I can mine diamond, gold, etc?

Yes, I tried using my pickaxe on my ores and did not get the drops from them.
