Doesn't quartz also do straight lines pretty much always?
Based on the two large mostly clear crystals from different parts of the world I'm (figuratively) holding, "yes" would be my answer. Although most quartz I come across in the wild is the cloudy chunky kind.
Selenite has a very straight crystal structure. It can even splinter.
Every crystal or crystal like structure does straight lines, no?
Diamond looks to be pretty jagged/rough, but I guess even it does have some straight lines on it.

Yes, though it it a bit funky.
Quartz has an octagonal crystal structure, which is the only thing distinguishing it from regular glass. Both are silicon dioxide.
If you melt quartz and let it cool, it will just be regular glass with an amorphous crystal structure. Conversely, if you melt glass and mix in some ground quartz, it will crystalize around the pattern and become quartz.
Snow is just straight lines
