    Found them allot when i was mining diamonds. We called it *board* diamonds. Used after excavation as pan testers. Or sorting testers.

    This is not close to what a common diamond is. The easiest would have been using a diamondtester or cut the stone and use a refraktometer

    There is no other mineral as hard as diamond.. diamond density differs depending on the depth of formation.. i find 10, 10+, ++, +++

  • koolkitty8989

    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.

    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 5 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 3 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.

    Hey Cody.
    Wikipedia says, that natural diamond has more than 5 times the thermal conductivity of copper - 2200 W/(K*m) vs ~401 W/(K*m) for copper.
    Monocrystalline isotopically pure diamond (99,9% C12) has thermal conductivity of 3320 W/(K*m).
    As far as I'm concerned, the latter value is higher than graphene, and highest known for a solid material at room temperature.

    Please explain the volume test. I don't understand it. How does displacing water in a cup increase it's mass if the rock is suspended by the wire.

  • Mshojat
    Mshojat 5 months ago

    I totally think that a water jet could for sure "cut" that. It might not cut it _straight_ but I still think that it would certainly break, since it's not a pure, "perfect" diamond, but rather full of cracks, holes/bubbles, and contaminants.
