Jewels are the game's premium currency. There are a few ways to get them for free. Log in daily to earn 50 jewels the first two days, 100 jewels on the third and fourth day, and 200 jewels on the fifth day, at which point the reward will reset. Create or join a party to play with your friends. Joining your first party rewards you with 100 jewels. As the storyline progresses you will occasionally be rewarded a bonus chest that contains jewels. These chests are available every five new quests that are completed.
