Do you think expensive jewelry worth the money?

I bought this diamond like ring for 5 dollars and someone asked me if it’s real diamond. It’s sparkling and it looks real. A girl asked me the same thing when I was wearing fake diamond ear ring. I mean is it worth to spend millions of dollars for real diamond? Cheap ones do the same thing and it looks real. Why buy the real one?
