As usual, I agree completely with Anita. At least it has a black background. I've seen pieces adveritised as nerox a petoni which had no black.
I took the same risk on a big vase which I thought be nerox a petoni, but no joy. I should post a picture some time in case somebody can tell me what it actually is. It does look and feel like Murano.
My commiseration.
