The effect is arresting: The gem, normally brilliantly faceted, appears as a flat, black void. The artwork, conceived by Diemut Strebe, an artist-in-residence at the MIT Center for Art, Science, and Technology, in collaboration with Brian Wardle, professor of aeronautics and astronautics at MIT, and his group, and MIT Center for Art, Science, and Technology artist-in-residence Diemut Strebe, features a 16.78-carat natural yellow diamond from LJ West Diamonds, estimated to be worth $2 million, which the team coated with the new, ultrablack CNT material. They are also showcasing the cloak-like material as part of a new exhibit today at the New York Stock Exchange, titled “The Redemption of Vanity.” The researchers have published their findings today in the journal ACS-Applied Materials and Interfaces.
The foil captures at least 99.995 percent* of any incoming light, making it the blackest material on record.
The material is made from vertically aligned carbon nanotubes, or CNTs - microscopic filaments of carbon, like a fuzzy forest of tiny trees, that the team grew on a surface of chlorine-etched aluminum foil. MIT engineers report today that they have cooked up a material that is 10 times blacker than anything that has previously been reported. With apologies to “Spinal Tap ,” it appears that black can, indeed, get more black.
