Indus Valley 400 yr old Bead Magical

I know I have not done justice to this bead and I will try to come back and make better pictures. This is a truly lovely bead, for those who really are attracted to the magic of ancient beads. I will put it onto a black cord with two sliding knots so that you can wear it. Even though the picture is not perfect, you can still see how pitted it is. Just a much loved bead. It has to be glass, but it is so dense, there is mystery here. You can see a strange dip by one of the holes.
