It's about two brothers who look for their missing parents and then find out they are spies and at the end of the movie the bad guy turns to stone after looking in a mirror that grants the person their deepest desires

That sounds like The Hunters:
The Hunters (TV Movie 2013) - IMDb (http://www.imdb.com/title/tt2963232/?ref_=nv_sr_1)

One difference is that the parents track down artifacts from fairy tales.
