I don't think your a scammer...I've just been scammed before on a gold chain that ended up being fake...and so I am skeptical....I'd buy the lot for $500 if i was 100% sure it was real....if fake it wouldn't be worth $50
If u can get pics of each piece weighed out either in penny weistamps ght or to 1/10th of a gram and get pics of the stamps(like the 14k, Italy, etc stamps) on it, then I'll likely buy it.
