Gemstones, Gold, etc.


I was wondering if anyone knew how to make proper gemstones & gold for the above image.

Well the gold isn’t that much of an issue, it looks shady here due to the poor light - but any help is welcomed.

I am looking specifically for how to make realistic

Rubies
Diamonds
Emeralds
and
Pearls

I already know about the gemstone addon - extra meshes. It’s more the texturing that has me stumped as most gemstone tutorials don’t show a rendered image and/or how to texture the stone.

Or would it be better to “cut” my own stones through some youtube videos instead of the gemstone addon? Is there any difference.

The biggest stone is going to be in the center of the triangular square other than that they are small like shown.

Or would compositing be better? If compositing better give some help cause that’s beyond me.

I am pretty sure I’ve seen some materials for gemstones and such posted in this thread, http://www.blenderartists.org/forum/showthread.php?278285-Yet-Another-Thread-about-Cycles-Materials

I would check these materials in blendswap:

Diamonds
