The Folly of Vanity is a 1924 American silent drama film codirected by Maurice Elvey and Henry Otto and starring Billie Dove and Betty Blythe.

As described in a review in a film magazine,[3] Alice (Dove), a beautiful young wife, loves jewelry and spends some money intended for other purposes to buy an imitation pearl necklace.

Ridgeway presents his guests with expensive jewelry as souvenirs and, unable to persuade Alice to take any, insists that she wear a beautiful pearl necklace to restore its lustre.

The whole crowd is invited on a yacht cruise where Ridgeway is attentive to Alice, while a wealthy widow (Blythe) attracts Robert.

A witch (Drovnar) discovers that an imprint has been on her neck by the pearl necklace, a mark of vanity, and Neptune orders her cast out.
