There actually is such a thing as diamond dust that comes from real diamonds, but this isn't it -- at least according to the nice salesman who was minding the store. He was sorry to tell me, he said, that it's actually crushed glass, adding that Hirst had tried to use the real thing here but it didn't work aesthetically.
Hirst is as much known for his stupendous marketing as for his art. It's on full display here, and not just with the fairy dust. The print is an edition of 1,000, so at $2,000 per he's aiming for a cool $2 million. With about 700 sold, according to the salesman, he's well on his way.
