Sugar sapphires are pink jewels that were seen in The Heist. Chowder sniffs one out and Mung explains that the sapphires are hard as rocks until you bake them (as Chowder tried eating one but broke all his teeth), then they become the sweetest dessert anyone's ever tasted, which was what made them so valuable (as well as being super rare). Endive has hundreds of them under her kitchen.
- In real life, sapphires are actually blue, but the sugar sapphires are shown to be pink. The reason for this is unknown.
- Sugar sapphires start out as sugar coal deposits, but when there's a lot of pressure (like because of stomping for example) they then become precious sugar sapphires.
