It's basically a chunk of carbon.  But apparently there's a lot more to a diamond.  Pliny the Elder thought pretty highly of them.  DeBeers made us want them.  And they're measured in C's.   Why are they measured in carats?  Who decided a D rating means it's colorless.  And what's up with Chocolate Diamonds?  So many questions.  If you have 20 minutes, you may have some answers.
