They range from 5000 GP to 220500 GP other than the legendary one which is priceless. There is a wide range of powers they grant. From bonuses to things like hex DC's, class ability, feat, powers usable x/day, to things like tremorsense.

Closing thoughts. The artwork is appears to be color photo's of real gems. Editing and layout are good I didn't notice any errors. Now before I go further I feel I need to point out, I honestly strongly dislike Ioun stones. I think they are at best boring to down right silly personally. These stones are a lot more interesting than the default ones which is a huge plus. But they still use the same mechanic of orbiting around your head, but that's to be understandable. With that said these are well done and almost, almost make me like them. Enough anyways I might figure out my own way to use some of them. I do wish not all of them looked like gems more or less though to give a little more variety. So what's my rating? Well if you are a fan of ioun stones then I think you will really like this book, so I am going to give it a 4.5 star review.
Trust me, I'm a Succubus.
