All of Star Sapphire's special abilities stem from the enormous Zamoran star sapphire she wears on her brow. Among its known powers are:
Spinning Cloth * Sewing * Agricultural Field Work
The Secret Society of Super-Villains
Star Sapphire was once Remoni-Notra, a poor working girl on the medieval-type world of Pandina. The Zamorans, immortal women warriors who once lived on the planet Oa, always selected a mortal woman having a particular appearance to be their queen. They picked Remoni-Notra for her resemblance, gave her a star sapphire gem with magical powers, and advised her that it was her destiny to be their monarch.
Taking her place as queen, the new Star Sapphire learned that four other women across the universe had been given similar gems, one of them being Carol Ferris of Earth. Should any of them have choosen to become Star Sapphire, she would have come to Zamora and battled Remoni-Notra for the throne.
Remoni-Notra decided to eliminate her potential competition and traveled to Earth to find Carol's star sapphire. Unfortunately, she found no trace of it, nor any memory in Carol's mind (the Zamorans had decided that Ferris was unworthy to be their queen and removed her memory of being Star Sapphire). She took on two identities, Camille the real estate agent and Debbie Darnell, romantic interest of Captain Comet. As Star Sapphire, she joined the Secret Society, hoping it would enable her to track down the missing gem.
