Diamond material/appearance

I'm trying to do some renderings of jewelry, and was kind of surprised to see that neither PW nor PV360 have a diamond material - the old PW did.  The Reflective Clear glass looks like... glass.  Lacks the "fire" or sparkle of a real diamond.

Any of you Modo users have anything?  I thought I saw a thread on here where you could use Modo materials in PV360; if you wouldn't mind sharing the file I'd be very appreciative.

Thanks,

Matt Graves
