Ancient dZi Beads from 2500BC to 500AD

I am working on a facebook blog that will be dedicated to displaying in great detail the difference between real and faked dZi, and hopefully educating the unwary buyer of the potential pitfalls out there.. It is full of high quality close-ups of genuine old beads clearly showing all the signs of age and wear, and comparing them to the fakes and showing the differences between them.
