A movie about a woman-thief that can't be caught

Question

I recently watched Catch Me If You Can (2002) and my mother told me she have also watched a movie a bit like that, but she can't remember the name. So here are some points that she does remember:

• The convict is a single, very rich woman
• She mostly steals (eg: diamonds) from museums and high-scale jewelry shops
• She cannot be caught (much like DiCaprio in Catch Me If You Can)
• She changes her identity all the time
• Maybe from the 80's or 90's (not sure though)

So does anyone know of a movie like this?

Thanks.

Answer 1

I don't think it fits that well, but it may be a try (be it only to exclude it for other potential answerers):

When talking about a woman thief, I incidentally thought about The Real McCoy from 1993, a movie where Kim Basinger plays a thief/safecracker. But she isn't rich or does it all the time for fun. She gets released from prison and wants to start a clean life with her son, but gets pressed to do another job by her former boss.
