I am fascinated by crystal minerals such as quartz, pyrite or the inside of
geodes. I have searched both povray and the www for information about
rendering examples as images or even animations. I have not found anything.

My knowledge is very limited in this area. I have found references to
crystaline structures of molecules, but that is not what I am looking for.

Here are some photograp examples, any suggestions on how to emplement
something like this in POVRAY?

Thanks,

You will need to know something about crystallography in order to build 
minerals. This site may be a good starting point:

This seems like the sort of thing that might turn
out OK by using "greebles".
By that I mean that you might randomly place a
bunch of individual crystal shapes together on
the surface of some object to get a jagged
crystal surface.

To make a geode for example? Yes, I think so.
