Thanks @Alex K. This has been driving me bananas! I've had all three on the digital scale and looked ar them with my steroscope on x10 mag. 

As a big fan of the Antiques Roadshow, I particularly enjoy the segment when Fiona Bruce has to identify the original item from the fake. I have a dilemma that I can't quite figure out if any of the three 39-45 stars that are sitting on my desk are fake. A good friend, who I trust his expert knowledge, has advised me and I'm sitting here with my loupe trying to figure it out. 

I would appreciate your thoughts on the trio below!
