I don't think so: the pictured mineral shows cleavage and quartz hasn't this property.
There are so many minerals that from pictures like these it's impossible to tell, there are more specific tests.

That's what I thought.

Back in grade school I probably could have identified it, thanks to the "Little Golden Books". :wink:
