Star Sapphire

This is Star Sapphire. Green Lanterns enemy from an immortal race of warrior women called the Zamarons, had chosen physically identical mortals from across the cosmos to serve as host body for their Queen, whom they called Star Sapphire. She is then given the Queen's symbolic weapon, a crystal resembling an actual star sapphire which grants the user powers similar to the power ring of a Green Lantern.

 

I think at one point as Carrol Ferris she also has a love/romantic interest with Green Lantern/Hal Jordan
