How are semiprecious stones dyed?

Not heat-treating, dye. Like this
. In the case of that rock, loads of pink color washed off after my friend put it under running water. But not all - I'm guessing the dye in the front of it was sealed in by the.. polish?
How do they get it in there? What kind of pigment is it? Is there any way to get it out of a rock, once it's in?
