Yellow gem

The Yellow Gem is a rare type of gem in the Crash Bandicoot series. Along with the other colored gems, this gem is very powerful and opens up secret areas.

Crash Bandicoot
In the original Crash Bandicoot game, where the colored gems were earned the same way as the clear gems, the yellow gem is obtained by breaking all the crates and not losing a life in The Lab. It opens up the Yellow Gem Paths in Lights Out and The Great Gate. Although the yellow gem isn't exactly necessary to get to the yellow gem path in The Great Gate, as the player can use the edges of the teleport pad to jump to the other side.

Crash Bandicoot 2: Cortex Strikes Back
The yellow gem appears as a rather tall one. In this game it can be obtained in Plant Food by reaching the end of the stage before the timer reaches zero. It opens up the yellow gem route in Sewer or Later and part of the multicolor gem route in Spaced Out. The yellow gem platform is also the widest.

Crash Bandicoot 3: Warped
It appears exactly the same as in Crash 2. It can be obtained by completing the secret route in Hang'em High, which opens as level 27 when the player collects ten relics, although this is not obligatory, as the player can get from the main path to the secret route with some clever jumps. It opens up the yellow gem route in Dino Might!, which in turn contains the secret warp for Eggipus Rex, and part of the multicolor gem route in Bug Lite. Again, its corresponding gem platform is much wider than the others.

Crash Bandicoot: The Wrath Of Cortex
The yellow gem has a slightly different model, it becomes more clear and smaller. it can be obtained by completing the death route in Gold Rush. It opens up the yellow gem route in Compactor Reactor.

Crash Bandicoot: The Huge Adventure
The yellow gem is located in Final Countdown. It unlocks a special area in Ace of Space, which is the only section of the game that uses the space motorcycle.
