Information on a Cartier Gold Paperweight?

I have something that I got an estate sale. It is what appears to me to be a paperweight. It appears to be gold, it has the Cartier emblem on the front and is signed Cartier on the back. It comes with a cartier box, and comes with a little bag marked Cartier. I really don't know much about this, any idea what it might be?|||I would suggest taking it to a Cartier boutique, maybe they can help you.
