How do I find rock wall options to cover a bedroom wall?

I am looking for an option to cover a bedroom wall in the era of my home (1895) to be an accent. I want it to look real but don't want the weight of real rock. Wallpaper is not an option. The faux rock seems to be very costly, compared to real. I don't want to put that much weight on the wall/floor and foundation.


Any suggestions would be greatly appreciated.
