cycles pearl material help

i’m trying to make a watch and i’m finish modeling, but i’m stuck on the pearl matherial, how does all of it is white but when looked in an direct angle to the pearl, there are multiple colours? and there’s a meaty colour hue on it,
i tried using the light path node, with a colour ramp, but it doesn’t work

If you are talking about viewing angles then you probably want fresnal/facing. I can’t see the light path node coming into play here.

Here’s a render and the blend if you want to look at the setup. It’s like 11 mb only because it’s got a big environment lighting image.

Subtle ramp shadings all over the place! :smiley:

I used this gemdat.orgas a reference and built a pearl shader group with an easy color selector and facet size. If anyone else thinks it’s ready I’ll post the blend.

Here’s a porcelain bowl full of pearls with that pearl material, all procedural.
