Here are some lovely websites which will help you track down specific refractive index's of materials or elements.
Refractive Index Databases:

Looks pretty usefull :)

Indeed. They even have a specific 3D section with "fine tuned" indexes for work with 3D programs, where I guess real world values may not be the best translation.
For example, here is the 3D version of gold with a index of n = 0.65663 https://refractiveindex.info/?shelf=3d&book=metals&page=gold
I have (once upon a time) posted a link to an index, but this is more comprehensive. But for those wishing a simple list, here's another one (pdf): http://www.rendervas.altervista.org/modelli/IOR_Table.pdf (http://www.rendervas.altervista.org/modelli/IOR_Table.pdf)
Handy to have!

Thanks dune, I also found another database. I might as well throw this all up in the original post.

Also added another which has rocks and conglomerates from Department of Physics; University of Oxford.
