saffire

To get the sapphire you have to give the ruby to Celio and go to four island and defeat team rocket if you did then make sure you have a Pokemon that knows cut and take the ferry to six island and then take the path that goes down. Then go to the left and take the 2nd staircase you see. Just keep on going and soon you should be at a door with braille letters. Use cut. You will be in a place called dotted cave. When you get there go down the holes. I forgot which holes to go down but you should figure it out quickly. Once you get to the sapphire a scientist will come up to you and take it. Then you have to go to five island and go to the rocket warehouse. Go inside and make your way through it. Then you will have to battle two admin rockets and the scientist who is very easy. Then he will give you the sapphire.
