Evolution stones are used to evolve certain Pokemon.
You can buy evolution stones at the Celadon City Department Store on the 4th floor.
When you buy or win an evolution item, you have to go to "My Pokemon" from the Trainer HQ tab, scroll down to the Pokemon you want to evolve, and look at the far right, there should be an option that says "Evolve me!" Click that, then click the "Evolve!" button on the next screen. Hope I helped!

Evolution stones appear randomly, not just in the center of the screen.
You go to your bag and select one of the evolution stones you have, then you select "Use" and the screen will go to your Pokemon party. Then you select the Pokemon that is able to use that particular stone to evolve. If you don't have any of the particular Pokemon that uses evolution stones to evolve, it won't work.
