The Star Sapphire Gem was a precious stone of alien origin, which seemed to be a star sapphire, or at least something similar.
Whoever so wore the stone possessed incredible magic-like powers.
Carol Ferris had one of these stones and took on the alter ego of Star Sapphire.
The stone originated on the homeworld of the Zamarons, which was an alien race that descended from the Maltusians.
