Hi
I’m not a jewelery designer so any help or tutorial on how to render this kind of parts is wellcome.
Micha??? 
My main problem is that I don’t have any idea on how to start and material configs. For example I started with the Micha “hdri_osvetleni” but I really don’t understand why his GOLD material doesn’t have any corold in difuse.
I saw the Matt scene (Matt’s Jewelry Gallery) and he has a compltelly diferent scene from mine.
Anyone wants to create a good starting tutorial for jewelery render?
Thanks
Sergio
