The Gem of Amarrah was a legend amongst vampires. The Gem rendered the vampire who wore it invincible. Vampires combed the world for the Gem, but none found it and it was concluded that the Gem must be a myth, not unlike the Holy Grail. In The Harsh Light of Day, Spike discovered the Gem in a ring sealed in an underground crypt in Sunnydale. After Buffy got the ring from Spike she entrusted it to Oz to deliver to Angel, who destroyed it as he was worried it might get into the wrong hands.
