I doubt she paid that much at the market in Beijing, but it is possible. They look to be commercial grade freshwater with some sort of stone. Can't really tell on the stones, but I am guessing she likely paid somewhere in the neighborhood of $30 to $40 for the two obvious pearl pieces. The first piece isn't pearl though, so I have no idea what it could be worth. In the states the value would definitely go up depending on how they are resold, but I would guess a boutique would retail them for around $150 to $200.
