Gems and jewels often serve as a Macguffin in fantasy stories. Recovery of the myserious gray Arkenstone is what motivates the dwarves on their quest in Tolkien’s The Hobbit, and in his Silmarillion, the Silmarils that embody the light of the great tree. Similarly, the theft of the rose-colored diamond called The Pink Panther motivates Inspector Clousseau in the movie of the same name. Kryptonite serves to make Superman vulnerable in the comics and the movies. Adamantine, a fictional mineral stronger than steel, makes the ultimate suit of armor in the Advanced Dungeons and Dragons universe. Dilithium crystals power the USS Enterprise.
Gems can also add evocative local color. Opafire, a rare gem, was prized by the Padishah Emporers in Frank Herbert’s Dune.
If you’re curious, a random gem and mineral generator is here and can be used. But I like to think my random gems sound a lot nicer.
