Diamond historical prices

[DCR]

Im looking for historical diamond and rough diamond prices. I mean price lists of previous years. Is it possible to find something like this? I want to do mathematical analisys of them.
Thanks in advance.

Rapaport publishes historical diamond prices annually and goes back up to 10 or possibly even more years in the issue which covers this topic. Maybe someone has copies of this for you.
