For some curious reason, the most productive mines seem almost always to be found in inaccessible regions. The world's top producer, which only went into full operation in 1987, is the Argyle mine in the remote northern section of Western Australia. Last year, it produced more than 35 million carats, though most of them were of industrial quality. They may soon have new rivals as twin moves to cut cost and build employment encourage new cutting facilities in Bangkok and even in China, which is just beginning to dabble in the art. London remains the focal trading stop.
Diamonds are hard beyond belief.
Of the 100 million or so carats mined each year, those in the very top grade number in the hundreds. What's more, about half of a rough diamond's total weight is lost in the cutting process. Diamonds personify value. The luxury car, the private plane, the regal fur are all passing pleasures. Diamonds are forever.
