Yes all that is true, but the chinese don't consider that copies are not "fake", but also a sign of admiration for an artist or a piece. that is true since thousand of years. The copies always existed in China. I know that, now, for example, the ceramist make poetry with the same methods as formerly, and it is very hard to see the difference. Of course the border between the fake which is made to deceive and a copy by admiration, is very thin!!!! But there are also true old pieces, beads, or jade, or ceramic. There are true experts who are not dishonest. E-bay, unfortunately, is not the place where are the best true pieces!!! there are many many fake beads, for example. The Dzi are a world!! and all the dzi I have seen were fake. The true dzi is so expensive!!! it is not on ebay!!
