Lindsay Lohan just walked out of a BIGTIME meeting with a major celebrity jewelry designer -- as well as key members of her team -- in an effort to kick-start her post-rehab career.
Lindsay's business date was with Pascal Mouawad -- a jeweler who's worked with stars like Heidi Klum and Nicole Richie.
We're told the two sides discussed the possibility of creating an upcoming line together -- the second time they've talked about teaming up. Back in 2009, they kicked around the idea ... but nothing ever came to fruition.
However, this meeting was all business -- because after the jewelry talk, we're told Lindsay's top people (lawyers, managers, etc) strategized about upcoming film projects and other career moves.
According to our sources, Lindsay has "multiple scripts" to consider.
