As a kid, I used to use a magnifier to light paper on fire and harass insects.  But I was curious to know what would using a magnified light, similar to the aforementioned, result in if it were focused on a crystal of salt?  Or perhaps a diamond?  Thanks!

Hot  salt, which would melt if you got it hot enough (about 800C)
You can set diamonds on fire if you get them hot enough. If there were no air then they couldn't burn, but they might turn into graphite (which is more stable at the sort of pressures we normally encounter).

About focusing magnified light at a diamond crystal, I would recommend not to have your face in the reflected light trajectory  :)
