When Anyanka arrived at Sunnydale High School, her vengeance demon pendant attracted Cordelia Chase's attention, asking if it was from the luxury fashion company Gucci. Anya denied it and explained: "it's an actual old thing, sort of a luck charm my dad gave me". The explanation hid the reality of it being a thousand years old magical amulet given by her leader D'Hoffryn.
Anya lent Cordelia the amulet, saying "I think you need this more than I do right now," while motivating her to make a wish. Once the wish was done, Cordelia appeared in an alternative reality still using the pendant, where Rupert Giles took it from her corpse in order to research about it. In his books, Giles found out it was the Symbol of Anyanka, and that one should destroy her power centre in order to defeat her, reversing all granted wishes and rendering powerless – and human – again.
First unaware the vengeance demon's power centre was her amulet, the Watcher invoked Anyanka, who appeared with her own pendant on her neck. While fighting, he noticed the amulet had an unnatural green glow, so he ripped her necklace and broke it with a paper weight against a table. The destruction of the Symbol brought the main reality back seconds before Cordelia's wish, but Anya had no power to comply it anymore.
After Xander Harris left her at the alter, Anya was once more offered her job as a demon by D'Hoffryn. She accepted, and received her pendant, which she maintained under her shirt when she wanted to trick the Scoobies into making a wish against Xander. Her new amulet was a light green stone, with oval design and silver chain, similar do Halfrek's.
