    Could someone quickly explain how the water volume test works? How does putting something into a glass of water on a scale allow to measure the weight of water displaced if its still in the glass and on the scale?

    hello Cody!
    I have been interested in an experiment involved in making synthetic diamond. The experiment is kind of famous but i have never seen anyone do it.
    things that are used is a real diamond (very little amount) called a carbon seed.
    Other stuff are also used such a grafite and so on..
    U put it in a microwave though and let it form a bigger diamond from the other elements included.
    i would love if you do read about it and try to do it.
    I am a new fan/subscriber. :)

  • koolkitty8989
    koolkitty8989 5 months ago

    Just barely too dense to be silicon carbide, too, which would be the go-to diamond-like material. (refractive index included) Plus the thermal conductivity isn't nearly as high (though still fairly high, in the ballpark of copper or higher depending on the crystal form), and it's a semiconductor.
    Wait ... diamond should be 2-5 times as thermally conductive at copper near room temperature. So if 'about the same as copper' is the benchmark, silicon carbide would fill most of these qualifications. (it'd need something to bump the density up beyond 3.21 g/cc though)

    Suggestion: Put a microwave oven with some graphite in it into your big vacuum chamber, vacuum it down, refill with a mixture of hydrogen and methane, and turn on the microwave. Theoretically, it should deposit diamond on the graphite.

  • Richard Robertson

    Cody, I didn't have time to read all 759 comments, so someone may have already suggested this simple test. Place the stone in a cup of water and have it X-rayed (radiographed) at a local veterinarian's office. Vet's are easier to deal with than dentists or M.D.'s for experiments like this. If it is a diamond you would barely be able to see it; if it is a zircon it will stand out like a piece of lead (almost). Interesting video, as usual, Cody.

  • Mcchuggernaut
    Mcchuggernaut 8 months ago

    Cody man, that diamond isn't "a diamond". There are so many inclusions that it may as well be a piece of sedimentary rock made up of a diamond sand stuck together with a bunch of other crap. It isn't going to behave like a mostly pure diamond crystal lattice of the same size would behave. It will be MUCH weaker than a gem-quality diamond. If you stomp on a piece of sandstone, it will crumble to bits. Try the same thing with a solid quartz crystal (Which sandstone is primarily made of) and you will just break your foot. The water jet might not "cut" that stone, but it WILL blow out all the other junk holding that diamond sand together, either blasting it apart or appearing to "cut" it. Just my two cents for your consideration.

    • Mcchuggernaut
      Mcchuggernaut 6 months ago

      The definition of a diamond: A solid form of carbon with a diamond cubic crystal structure. This "rock" is what you call a "matrix" with diamond inclusions. And you are right, Cody is well educated, and a chemist. But do you know what I am? A computer tech grad with a minor in GEOLOGY. Sit down and shut up, you might learn something. Science is collaborative, and people specialize in different fields because it is impractical to be taught everything about every existing subject. That's why there are electricians, plumbers, and quantum physicists (instead of just generic "smart" or "skilled" people) doing specific jobs they are specially trained for. A physicist may be smart, but I might not want him wiring my house, fixing my toilet, or troubleshooting my computer.
