Caution is understandable given that many Murano looking pieces were made elsewhere. However I have seen this kind of hotworked pull to form a cigarette rest many times in pieces which I have no doubts are indeed Murano.
As to the colour, I have owned a number in this reddish orange, which I presume is selenium based and don't see any problem there. These pics look overexposed or perhaps brightened rather too much which perhaps accounts for your reservation there Anita.
Since getting a new TFT screen I find that several of my own pics look overbright on it. I have noticed the same with a friends laptop.
