Sorry just need an answer to my question about the platinum rings before I post up. And I will need a ruling to see if they are used up in the casting or are reusable it doesn't say. (PFCR- pg. 342)

Oh, I forgot to answer this. I think the simplest method is to ignore the intrinsic value of the rings and say that you need two specially prepared rings for the spell, but not that they are worth anything beyond a couple of GP for other purposes. That way you can cast the spell without worrying about additional issues of monetary value.
