The world’s most expensive objects: by weight

Different objects' cost by weight

There was probably never any doubt, but it is striking to learn by just how much diamonds trounce everything else in the realm of expensive stuff. We took a bunch of high-value objects - such as paintings and buildings - calculated the price per kg, then compared this with the value of various fungibles. Those “chunks of coal made good under pressure”, as Henry Kissinger called diamonds, are without peer - even when you consider just an average one, retailing at around £6,890 per carat. (Our benchmark was a “G” colour with “very small inclusions”; a “D” would have cost more.) Raphael’s The Madonna of the Pinks came close.

It probably suffered by virtue of being painted on a yew panel (weighing 800g), and one suspects the right Picasso, on canvas, would give diamonds a run for their money. Of the luxury foodstuffs, it’s most extravagant to order the prized white winter truffle from Piedmont, which is considerably more expensive than the world’s rarest caviar - almas - from the albino beluga sturgeon. But if they come at a premium, spare a thought for the owners of the Green Monkey, which, when he was bought for $16 million in 2006, was the most expensive racehorse ever sold - worth more than his weight in gold. He never won a race.

    Antimatter. The Large Hadron Collider, total cost approx £2.6 billion, can produce one billionth of a gram of the stuff a year. Assuming a billion is 1,000,000,000, the cost per kilo would be £26,000,000,000,000,000,000,000,000 or 26 septillion quid.

    The price of Class A drugs are rather expensive, fitting in between 2 and 3 on this list.

    Cocaine costs £51,659 per kilo; heroin costs £75,750 per kilo.
