In The Black Magician Trilogy, when introducing Sonea to the blood gems, Akkarin states that he has three blood gems.
- One is with Takkan
- One is with Lorlen
- "One with a friend in a useful place"

A quick google search hasn't revealed anything conclusive.
EDIT: It looks like the answer may be definitively revealed soon - Canavan is hosting a competition on her blog with this exact question as the competition question.
