And for even better images, if there's an "s" beside the flower, use that. But don't have the camera more than a foot away.
I have one Azurene pwt, signed by MH. It is not cased at all. I'm not sure if this is the normal case or not, given i have very little interest in pwts. Most Azurene bits are not cased. (unless they are Fish vases - and then, only partially cased, by the "wings").
Sometimes Azurene is fumed to give an iridescent sheen.
