They sure are, Debra -- beautiful!!
Patty -- go to my thread from today about Irises in my 2013 garden. On the first page, there are photos of *Magical* and *Black Magic Woman*. If you enlarge those, you'll see diamond dusting on both the standards and falls of Magical, and on the dark standards of BMW.
If the Iris has diamond dusting, and you photograph it in the sun, that's when you'll see it!
