Alexis Neiers is charged with one count of felony burglary ... for allegedly stealing two beaucoup expensive watches from Bloom's house -- which, along with some other items, were worth an estimated $500,000.
Interesting ... sources tell us Neiers turned down two plea deals from the L.A. County D.A. -- one for 1 year in county jail, and another for 6 months in jail. She's now rolling the dice and the stakes are 6 years in state prison.
Neiers' trial starts Monday.
