It is hard to get a large amount of gems just by going through everyday Animal Jam life, and occasionally playing games. What I do to get thousands and thousands of gems at a time takes a bit of work and is not a glitch or hack. Turn on some music,(optional) and go play the Animal Jam game Falling Phantoms. Make sure the music your listening to is on an automatic playlist. By the fifth song, stop playing Falling Phantoms and check your gems. You should have at least two thousand gems if you worked hard! Do this maybe twice a week, don't spend too many gems on anything, and eventually you could even have millions of gems! Hope this helped!
