The Necklace I have says 14k and Italy.It looks like it is tarnishing a little bit,but it doesn't say anywhere on it that its silver... I looked for 925 and I looked to see if it was plated.. But all it says is 14k italy.So I'm convinced its white gold.Any ideas?

It is probably white gold at l4K; european gold is more pure then on the north american continent.
