For more on the Diamond industry, try this 1982 article from The Atlantic.

It features a very interesting history of the way(s) in which this actually fairly common item has been marketed as though it were incredibly rare--a history which no doubt plays directly into the phenomena explored in the new movie.

As an echo of the article's title, I'll pose the question--has anyone here ever tried to resell a diamond?  They don't really take them back, you know, which ought to say something about the notion of "value."
