in pokemon firered where do you get all the gems???I need help cause i don't have a clue!

Go to(on the right)Five Isle Meadow(Five Island)and get though the Rocket Warehouse get though it and you'll find one.Next,go to Six Island(go down)and you'll find a cave...

The picture below you'll probly need,it's the Rocket Warehouse

First go to Mt. Ember on One Island and there are two Rockets, they will say a password and leave ,there will be a cave, go through it and there will be the ruby. Then the guy in front of dotted hole on Seven Island(I think it is seven) will leave, use cut on the door and enter and go through the holes in this order: up, left, right, down, you will find the sapphire than the man will steal it and tell you the second password. Then go to Five Island and through the meadow, enter Rocket Warehouse and find your way through, fight someone called Admin, she will switch a pad, so go heal, come back fight the second Admin and then the scientist and he will give you the sapphire.
