It really will depend on whether it is a mined rock with this particular mineral in it, a powdered, purified mineral, or a laboratory prepared precipitate.  Your textbook may have pictures you need, depending on what you need the info for. 

Failing that, like sjb: said, you'll have to Google image search it, with the caveat that you'll get a bunch of pictures, but you'll have to know which one you need.
