Sometime it's on the registration, Mary Ann. I don't see it registered much, though, especially on ones I know have it. Maybe Lucy is speaking of some other place they mention it.
I had a Jedlicka iris that I received as a bonus one year that was heavily diamond dusted. I will have to look up the name.
Here's a link to some nice pictures of diamond dusting:
