The series of short stories I am trying to remember are probably from Analog magazine or perhaps Asimov's or The Magazine of Fantasy and Science Fiction. I subscribed to these around 10 years ago.
I recall a series of stories about a woman (or man?) who might have been a miner in the outer parts of the solar system. She had either an implanted computer chip or a suit that became self aware.
She didn't want to go back to Earth because she didn't want to be found out, so she studied and she took mining jobs on the edges of civilization.
In one of the stories she was stuck on some asteroid that turned out to have a huge diamond inside it.
