Gem

Gems are almost as important as Crystals, however less valuable, and if the player gets every single gem, s/he usually gets some sort of award. There are about 45 gems in a game, except for Twinsanity with 100 and CTTR with 5. It has appeared in all games except the home console version of Crash of the Titans (They did appear in the DS and GBA versions, however).
