Clear Gem

The Clear Gem is the most common type of Gem in the Crash Bandicoot series. While it is often called the Silver Gem, it's known to be a diamond. In most (platform) games a clear gem is acquired if the player manages to break all boxes in a level. From Crash 2 onwards it might also be a reward for completing a secret area.

In Crash Bandicoot Purple: Ripto's Rampage Clear Gems are awarded for completing a Bonus Round or, if a mini game contains crates, breaking all of them and sometimes both.
