Pearl Material

Would anyone know how to go about making a white, pearly, iridescent material?

Anybody, pearl materials?

How about the iridescent texture at the bottom of this page? Maybe just some color changes?

Looks good, but it doesn’t say how to make it. (Other then saying what kind of procedurals they used.)

[Edit] Oops, just saw the .blends at the top of the page…

At the top of the page there are some blend files to download

Cool, looks like I may be able to use that material straight out of the box…
