It's really well known. There are articles written up about it every few years. It gets the occasional pop culture shout out.
We could split hairs for awhile and debate about how well known it is, or whether "Joe Sixpack" in Des Moines knows about it. But it's far from obscure.
I'll grant you that a lot of the major demand drivers (young couples, new money, etc.) probably don't know, or at least don't care. And that might make all the difference.
EDIT: Seems we both edited our posts at the same time. I think the Asian theory is interesting, and it might be the most savory / least fishy driver of price increases. Perhaps the "Joe Sixpack" of Shanghai, newly monied and with very few reasonable investment options in his home country, is buying diamonds left and right. Wouldn't surprise me. Either way, it seems odd that the cartels wouldn't go head to head in Asia for the big prize here, unless they reached a gentleman's agreement on territories.

An edit-off at 10 paces. Draw!
I think the whole thing is fascinating. From a marketing perspective it's amazing how De Beers manufactured demand for diamonds out of near nothingness.

This is an example of mutually assured destruction at play. The big players can't go head-to-head selling what is essentially a commodity good, without price cutting which would eventually lead to diamonds being sold for their true value. None of the players are interested in that.
