Basically what we call "crystal" and "Glass" is really bad use of terminology. Crystal means there's long-range order (long range being many atoms). Metal, for example, has a crystal structure (under normal conditions).

The fun part is glass is (a lack of) structure (amorphous), and metals can be a glass (though it won't be transparent). Furthermore, even polymers (plastics, but really tons of things are polymers) can be glassy or crystalline.

Even the normal use of the word "crystal" doesn't automatically mean that it's transparent (but in the naruto episodes, it was). Also, Ice for example is a crystal.

Sorry, had to get that off my chest. Been bugging me for a while now that language makes no sense.
