Hmm. Let's see what others think. Set in stone and or set like stone? I think it could be stronger than this.
I was set on fire by your glorious smile? When I first saw stone, I thought Medusa. Lol. Not sure it works.
Think on it. I'll have to watch that program or channel you were watching to get ideas like this to write about. Fabulous! : )
Hey Carl I really like that !!!!
"I was set on fire by your glorious smile", it really fits well with the overall imagery of hot sun, heat & desert etc. 
The programme reminded me of the unfinished lyric i've had sitting around for a few years now. I originally wrote it while lying on a sunbed in Egypt 
I had to delete the bit about continually swatting bloody flies & the immeasurable pain a guy feels after an hour on board a camel!!!
