Normally it doesn't happen after your initial 500 taps for 50 gems after the tutorial. You will still get gems from downloads, but those are dependent on how big the downloads are, so you don't have to tap for those. (Every xxx size downloaded will give you 1 rainbow gem, and your progress saves & continues with the next download).
