NASA Looking For "Diamonds In The Sky"

I Don't Believe in Imaginary Property writes "Scientist Charles Bauschlicher and his research team have found a new way to look for 'diamonds in the sky'. It may not be romantic, but diamonds shine especially brightly in the 3.4 to 3.5 micron and 6 to 10 micron infrared ranges, which should make NASA's Spitzer Space Telescope the perfect tool to see them with. Though less common and more monopolized on earth, diamonds are surprisingly common in outer space and the nanometer-sized bits comprise 3% of all the carbon found in meteorites. That means that if meteorite composition is representative of interstellar dust, that dust would contain about 10 quadrillion (1 * 10^16) nanodiamonds per gram."

      Difficult to know for sure, there's certainly some chance there'd be significant diamond or silicon carbide layers, but it's probably mostly metallic hydrogen with an iron-and-radioactives "core" core (probably much like earth's only bigger, despite the other vast differences). Due to the reactivity of carbon and hydrogen, most carbon present is probably as hydrocarbons in the atmosphere.

      Arthur C. Clarke noted that the idea that Jupiter's core was a gigantic diamond was inspired by an article in Nature which speculated that a solid layer observed in the compositions of Uranus and Neptune was composed of carbon liberated by intense pressure from methane.

      Laboratory experiments mimicking the temperatures and pressures found deep within those planets suggest diamond production is indeed possible, but would be more likely to be an agglomerate mass of diamond microcrystals than the yottacarat diamond solitaire envisioned by Clarke. Uranus and Neptune would probably make for better diamond production than Jupiter and Saturn due to a higher abundance of methane and thus carbon.

      That being said, recent research suggests that Uranus and Neptune are not sufficiently carbon-rich to have produced an appreciable amount of diamond after all.

    Actually, diamonds probably aren't worth the trouble of asteroid mining. Crushed diamond powder is cheap and plentiful right here on earth. It's only the larger chunks of diamond that are valued much, and even those aren't in short supply. The price of diamonds is only as high as it is because a cartel of the major producers work in collusion to keep the prices up. I suppose diamonds from asteroid mining might force them to lower their prices a bit, but it's unlikely that mining asteroids for diamonds could successfully compete with earth based diamond mining.
    Quite possibly if we do end up with asteroid miners, they'll be throwing away cheap carbon compounds like diamonds, in favor of useful ores like iron or nickel.

      Taking the density of diamond to be 3.5 grams per cubic centimeter, and these diamonds to each have a volume of about 1 cubic nanometer, the average interstellar nanodiamond has a carat weight of 1.75*10^-20 carats (One carat is 200 milligrams). The interstellar molecular clouds where we would expect to find these diamonds have a density of about 2 x 10^-22 grams per cubic centimeter; one cubic centimeter is about 3.4*10^-56 cubic parsecs, so there are about 5.9*10^33 grams of matter in a cubic parsec.

      Using the figure from the article, we could then expect there to be as many as 5.9*10^49 diamonds in a cubic parsec, with a total mass of 2×10^26 kilograms, and a total carat weight around 10^30 carats in a cubic parsec. Alas, not exactly gem quality material.

      Some notes:
      A well-formed 1 cubic nanometer diamond crystal would have about 175 carbon atoms total.

      Our solar system has a total mass of about 2*10^30 kg, 99.8% of which is the sun.

      The mass of the earth is about 6*10^24 kilograms.

      If split among the population of earth, your share of the diamonds in a cubic parsec molecular cloud comes to about 30 trillion tons.

      If you merged all the nanoscale diamonds in a cubic parsec molecular cloud into a single diamond, it would have a volume of 5.7*10^13 cubic km, about 50 times that of the earth.

    Yes, diamond powder is great for grinding and polishing hard things, like silicon wafers.

    Industrial diamond is manufactured cheaply. You can even find it on eBay for a couple of bucks a carat.

    The trick is getting a consistent grit/mesh/size so that you know how polished you can make your wafers.

    I worked with a guy in the 80's who had a side business making diamond grinding compounds for customers in the bay area - he would pre-load his secret mixture into grease-guns he bought at Sears. They were single use, he told me. I don't remember why, something about screwing up the seals, or maybe a used grease gun put contaminates in the grinding goop... anyhow he made really good money at it for some reason, there must have been more to it than meets the eye.
