The answer, pictured here, is a life-size platinum skull set with 8,601 high-quality diamonds. If, as expected, it sells for around $100 million this month, it will become the single most expensive piece of contemporary art ever created. Or the most outrageous piece of bling.

At home in Devon, Hirst insists it’s absolutely the former. “I was very worried for a while, because if it looked like bling — tacky, garish and over the top — we would have failed. But I’m very pleased with the end result. I think it’s ethereal and timeless.”

For Hirst, famous pickler of sharks and bovine bisector, all his art is about death. This piece, which was cast from an 18th-century skull he bought in London, was influenced by Mexican skulls encrusted in turquoise. “I remember thinking it would be great to do a diamond one — but just prohibitively expensive,” he recalls. “Then I started to think — maybe that’s why it is a good thing to do. Death is such a heavy subject, it would be good to make something that laughed in the face of it.”

The dazzle of the diamonds might outshine any meaning Hirst attaches to it, and that could be a problem. Its value as jewelry alone is preposterous. Hirst, who financed the piece himself, watched for months as the price of international diamonds rose while the Bond Street gem dealer Bentley & Skinner tried to corner the market for the artist’s benefit. Given the ongoing controversy over blood diamonds from Africa, “For the Love of God” now has the potential to be about death in a more literal way.

“That’s when you stop laughing,” Hirst says. “You might have created something that people might die because of. I guess I felt like Oppenheimer or something. What have I done? Because it’s going to need high security all its life.”

The piece is not exactly the stuff of public art, but Hirst says he hopes that an institution like the British Museum might put it on display for a while before it disappears into a vault, never to be seen again. Whether the piece is seen or not, Hirst will likely go down in the Guinness Book of Records as the world’s most extravagant artist.
