In a play about William Dewey, he was saved by a Fusion Gem from a Gem Monster. Little is known about her except for a very basic idea of her physical appearance based on the silhouette from the play.
Her lower body and upper torso appear to be reminiscent of Garnet. She also sports a huge mane of hair but kept in a proper hairstyle closely resembling that of Rose Quartz. She is depicted with four arms, while the temple fusion has eight arms, and Alexandrite has six.
In the play, she is portrayed as towering over William Dewey, his ship and its crew. Whether or not this is an actual attribute of hers or simply an artistic choice by Jamie remains unknown. However, the script used was edited by Pearl for accuracy, as she had first hand experience.
In Mayor Dewey's script, his ancestor performed the actions of this Gem.
Mayor Dewey describes his ancestor as growing to fifty feet tall.
