Amber

Amber is a type of gem. Besides Orange Torches, Crate Potions, Amber Gemspark Blocks and the Amber Staff it cannot be used to make anything else other gems can be made into, such as Grappling Hooks or Phaseblades. It can however be placed as a decoration like the other gems.

Unlike other gems, Amber cannot be found naturally in the Underground or Cavern layers, and can only be acquired by feeding silt, slush, or Desert Fossil into an Extractinator.

Trivia

 * Amber's original purpose, the Orange Torches, were apparently added because of a "really persistent nagging brit."
 * In real life, amber is fossilized tree resin, making it different from other gems' real-life counterparts in fact that it is much younger and made of organic material.
