Within DC continuity, an immortal race of warrior women were depicted as having the ancient tradition of choosing physically identical mortals from across the cosmos to serve as the host body for their queen. The woman they choose to serve this role is called Star Sapphire. She is given the queen's symbolic weapon; a crystal resembling an actual star sapphire that grants the user powers similar to the power ring of a Green Lantern.
The most prominent of them has been Carol Ferris, the sometime girlfriend of Hal Jordan, better known as Green Lantern. When possessed by the Star Sapphire gem she exhibits powers similar to a Green Lantern, including force blasts, a protective shield and flight. She was revealed to be only one of a series of Star Sapphires empowered by a race of females known as Zamarons. They have recently expanded their influence with the creation of a Star Sapphire Corps, also known as the Violet Lantern Corps.
