Aversis Vray 2.3 Tutorial - Render jewelry and diamonds in V-ray

I'm looking for this particular tutorial if anyone has it.

http://aversis.be/tutorials/vray/vra...-rendering.htm

It would come in handy, I'm sure, for not only myself but many others as it seems rendering diamonds and jewelry in vray seems to be quite the issue as far as my research has confirmed.

I have also posted this request on CGPeers.

Many thanks in advance to whomever can produce this!
