Other unique abilities of the Star Sapphires' rings include the ability to reveal the wearer's greatest love. They're also able to detect when a loving heart is embattled and in need of aid. By connecting the heart of the ring bearer to a true love in danger, the power of the ring can also act as a tether. Star Sapphires have not been shown to be particularly vulnerable to the powers of other Corps, however as their powers come from one of the farthest two sides of the spectrum their rings have greater control over their personalities.
