I read about that too, but sometimes glass or crystal can have the same effect, but the resulting image is not as sharp? And yes, if it's drilled- that's a no no. I've seen plenty of listings where they appear to be just clear beads being called POL.I think the biggest thing to watch out for when buying POL is that it is actually made of natural quartz. I have seen many advertised as POL but they are either drilled or made of man made glass/crystal. Real ones are made of natural clear quartz. There is a test I read about to check- when reading newsprint through the bead the print should be flipped upside down. Not sure if that is 100% accurate.
