Play the story and find gems like you find sealstones and daemons. If you win a fight and they have a gem, you get one gem, but if you lose, you lose a gem. If you are attacked and have five gems, you don't get a gem, because the sixth gem completes a set and give you an item or a card. 100 sets is 600 gems. I hope that helps.
