Amber

Amber is a gem acquired by placing Silt, Slush, or Desert Fossil into an Extractinator. Unlike other gems, Amber cannot be found naturally. Instead, Silt/Slush/Desert Fossil blocks must be fed to the Extractinator, where Amber has a 1.05% chance of being obtained (higher with Desert Fossils).

Amber can be used to craft several gem items, but unlike most other gems, it cannot be used to craft Phaseblades, Stained Glass, Gem Grappling hooks, or early-game magic robes.

Like all other gems, Amber can be placed on blocks.

Trivia

 * Amber's original purpose, Orange Torches, were apparently added because of a "really persistent nagging brit." in reference to Youtuber ChippyGaming AKA James Bennett
 * In real life, amber is fossilized tree resin, making it different from other gems' real-life counterparts in the fact that it is much younger and made of organic material. Such resin is called copal.
 * Amber is the only non-naturally occurring gem.
 * Amber is the only gem without a gem hook counterpart.
