Are we talking diamonds as in carbon / jewel or the weather condition? Diamond dust (ice needles, frost in the air, frost mist) is a type of precipitation composed of slowly falling, very small, unbranched crystals of ice which often seem to float in the air. It may fall from a high cloud or from a cloudless sky. It usually occurs under frosty weather conditions (under very low air temperatures.) http://nsidc.org/arcticmet/glossary/diamond_dust.html Apr 16 03, 2:01 PM

Black The team, led by Benedetti and Raymond Jeanloz, professor of geology and geophysics, ...inside a diamond anvil cell, squeezing liquid methane to several hundred thousand times atmospheric pressure. When they focused a laser beam on the pressurized liquid, heating it to some 5,000 degrees Fahrenheit, diamond dust appeared. "It's really cool to watch," said Benedetti. "When you turn on the laser, the methane turns black because of all the diamonds created. The black diamond specks float in a clear hydrocarbon liquid melted by the laser." http://www.berkeley.edu/news/berkeleyan/1999/1006/diamonds.html Every colour of the rainbow. Diamonds are most commonly known as being white or colorless, can occur in every color of the rainbow. ...the next step is grinding it down into the proper shape. This takes hours on a diamond grinding plate using diamond abrasive made from other diamonds and the diamond dust coming from the diamond itself. http://www.longnecker.com/Active_web_pages/story-diamond.htm Apr 18 03, 4:36 AM

Question #42317. ellie42 asks: What colour is "diamond dust?" Siskin answers: Have a look at these pictures to decide. I would say white or yellow depending on the location. http://www.sundog.clara.co.uk/halo/diamonds.htm Dec 15 03, 7:25 AM griffinj answers: Diamond dust, as in the weather phenomenon, is colorless. Any color it appears to have is due to the refraction of light. Diamond dust, the industrial product, is black or gray due to the color of the stones ground to make it.
