Goofs unreported in a great movie

Rating: Null/10 (11 October 2005)

I have just watched Titanic for the 7th time. I saw in in the movies when it first came out and it is without a doubt one of the greats. I have searched through the Goofs feature on IMDb and I can't find the following.1) When seeing the picture of herself on TV old Rose calls Brock Lovett and asks "I was wondering have you found the diamond yet" or words to that effect. Why would she ask that question when she had the diamond all along. 2) Lizzy Calvert says to one of the crew referring to Rose, "we met a few months ago" Yet Rose States later in the movie that she never told anyone about Jack Dawson, "not even your father" to her daughter or was she an unrelated friend....
