It is one of the two minerals on the planet which does not hold and accumulate negative energy, but dissipates and transmutes it, working out problems on both the physical and subtle levels.  For this reason it never needs clearing or cleansing.

Citrine is connected to the third chakra (solar plexus). Has been
called "the merchant stone." Assists in acquiring wealth and to
maintain the state of wealth. Useful in balancing energy.

This is the normal description.  It is also called the "Coyote Tear".
It works for ALL chakras as well, and is also a protection stone.
I have heard it is also considered a happy stone.
