"C faced crystals" ?

Would someone please explain to me what a "C faced" crystal is? I've been looking the net and have found a few, but I see nothing that distinguishes them from the ones that aren't "c faced". And I've yet to find a definition.

Many thanks to anyone who wades in on this!

Hum... Maybe you can find something here, is the best site for technical issues ( Seems to be a crystal habit):

I've found this in an article, talking about an specific crystal.http://64.233.187.104/search?q=cach...tut1-04.pdf+"C+faced"++crystal&hl=es&start=19

I'll try to find something about this

Thanks, Gaby. I took a look at the url you sent. I'm still not clear on what "C" faced crystals are, though.

I'll keep looking.
