everything will be fine it always is

I get this tiffany and co from my grandmother when she passed, but I would like to know if it¡¯s definitely real, how can I do this?

I saw lots of my favorite movie stars wearing tiffany & co, so I¡¯d love to have one too.

I get my discount tiffany jewelry repaired at a local jewelry stores cost about 20 dollars, it¡¯s not that expensive.
