    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.

    Hey Cody how much heat does it take to melt a diamond? Plz tell me.

      It doesn't melt unless under pressure, carbon sublimates at about 3915 K ​

    Why don't you use measuring cylinder to measure the volume of that rock.

    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.

    That's a Carbonado (black diamond). Is less denser than a diamond, that's why you got those numbers. Look it up.

    Cody, can you please make flux grown rubies using a calibrated kiln and a platinum crucible? I have always been fascinated by that process. It just seems like a cool thing to do. Thanks.
