You can get gems easily by completing the missions of the game.


You can also complete the achievements available, which will reward you interesting items!


Take a look around your village! You could find some free chests that sometimes can give you gems.


Also, check out the events and the minigames that can include gems in their rewards.

And don't forget that leveling up and expanding your village will compensate you :)

NOTE: If you don't see some of these features yet in your game, don't worry! Keep playing and you will get them at higher levels :)
