Give it to celio in 1 island
Get the crystals on 1,2,3,4,5,6,7 islands and bring to Celio.
After you have obtained both the Ruby and Sapphire gems, you should go back to One Island so Celio can fix the machine he's been working on. By returning the two gems, trade with the Hoenn region is unlocked (ie. you are now able to trade between your version and Pokemon Ruby, Sapphire and Emerald). The two gems do not unlock anything else, but clear a significant obstacle which prevents you from completing part of your National Pokedex.
