Is this Rock a Diamond? 

MiYo not enough material.

C Lau, as far as I know Silicon carbide is very rare outside of synthetic production, and pieces like that might not even exist, let alone sell for 120$. I could be mistaken though. It might just be solid crystals of SiC that are rare (just like larger diamond crystals)

Mshojat. Natural Moissanite crystal is very rare, but non-gem SiC is used extensively as an industrial abrasive, and also in steel making where a lot of it is recovered as slag: this could just be a raw chunk.. Diamond is pure carbon and quite conductive as is; SiC is a semiconductor and usually covered with oxide, so would be only slightly conductive or non-conductive, so this could be an easy test..

C Lau maybe well I was thinking that too when I saw him do the conductivity and scratch tests didn't knew about the density though thanks for the info

And going for water jet channel lol

yup

DDDestructo I was gonna say, "Who knew jolly ranchers were so high on the hardness scale."

Ikr

exactly

DDDestructo Same then I thought it was red glass

Reddit story time?

But it doesn't really look like a diamond, it doesn't smell like anything really, and it probably doesn't taste like anything really.

Guess the joke must've went over your head.

upvote my comment

I'm not from Haiti.

Long Dick Johnson He was talking to me... also, I got the joke. I'm not stupid.

Where? Can you post a video about it?

Is this a true story... OR A REFERENCE??

@@NiennaFan1 maybe uts real coz i also bought a stone (which was supposed to be a iron ore ) and it turned out to be a diamond ore worth 20million dollars

@@p.aofwolfxnade3941 LOL yeah right

@@p.aofwolfxnade3941 I know your lying because ain't no Diamond Ore worth 20 mil G😂

Not a bad idea. But you could also buy a carbon monoxid detector on a PCB and get a suitable Micro Controller too🙄. This things are no more as expensive, as they were some years ago 🤗. But the carbon dioxyd detectores are much more expensive. I have some gas sensors working with a MCR, to get nealy all necessary informations about the air quality. If I am not totally wrong, the carbon dioxid sensors seem to work with some UV-LEDs and some kind of a color or light sensor. I think, I had a look at the scematics and the manual and remember from them. 🐵 🙊 🙉

Paul 5 possibly a fellow from the water jet channel could figure this out

What's the lick test?

@@michaelriley8002 Reference to water jet channel joke, check it out, if you like codyslab you’ll like the waterjet channel

waiting for it myself so I can get the link.

check the description

Oh yes ! Cody try to burn it into liquid oxygen ! Pleaaaaase ! !

Andy T that sounds like a really fascinating idea.

This dude sounds like one of the water jet guys

yeah but it isnt doing anything to become a diamond

Steak Hair what a lazy rock lol

I have a black diamond

are yui assming what tool he uses ? (TRIGGERED)

penguin mykey im assuming you are not using the tool spellcheck 😀

Remember that the Moh's scale rates a mineral's *hardness,* not *toughness.* Hardness is how resistant a material is to abrasion. Toughness is how resistant a material is to fracturing under stress. Diamond, for example, is very hard but not very tough. It is fairly brittle when compared to something like steel, but steel is not as hard as diamond. That corundum may be incredibly brittle, similar to rock candy, but also very hard, able to scratch steel.

Diamonds are -forever- flammable

The diamond would disintegrate, though.

It *WAS* a diamond

Muzik Bike you mean EthoSlab

Haha maaaan that would be so random and awesome

He did post today a minecraft video on his second channel, maybe it's some kind of a hint?

i hope so

Same Person

only about 30% of diamonds glow under black light while many other stones glow so its not a very good test.

Is that due to different types of impurities?

yes

mee too

Johann okay thanks for being honest. Sorry I was aggressive

Diamonds are made of carbon, carbon is also what we are partially made out of, guess how much you can sell a human for rather than a diamond. You're worth more than that small piece of rock.

Alex Morrison and still my mom says i'm worthless

oh interesting. I've done research on various gemstones and such, but that was several years ago. I never heard of synthetic colorchange corundum.

cxx23 what about mossainity(SiC) it would also scratch Ruby (9.5) and is a better heat conductor than copper with a density of 3.21g/cm^3 so I think he might have a mossainite instead of a diamond

RB you can... make a glass cutter maybe

oh I have something else in mind for it.

...diamond bullet?

Cody'sLab diamond tip mining tool?

Diamond pick axe for his real life Minecraft series... ;-)

Bro it's cold I zip my jacket up when it's cold?? Lol

He doesn't have enough explosives.

It's impossible for a civilian

Ruby [Doc] HOW TO TELL IF A STONE IS A DIAMOND I CAN’T I AM DEAD (also don’t worry you’re all synthetically grown)

Drew Berger I’d certainly like to see that!

has* but yes indeed

if it's burnt away it would be HAD .

Both are kinda right, but clunky. It should read, 'If it burns away at 850°C you know it *was* a diamond'. Source: native English speaker

Nope, it should be "If it burns away at 850C you would know it was a diamond."

Nope again. It should read, “ if it burns away at 850°c you would know you had a diamond.”

Did you just assume the gender of macro shots?

More like gay4pay

diamond is not a mineral

Marie, could you please check them for damage?

Cody'sLab it's a Breaking Bad line, though still incorrect in this case

How is diamond not a mineral?

Diamond is a naturally occurring crystalline solid with a definite chemical formula and structure. How is it not a mineral?

if I am not mistaken, he sent crystalised honey to hidraulic press, and AvE sent him gold squares which he tried to cold weld in vacuum

well spotted, i forgot about those :P

Honestly colin has turned himself into a propaganda more or less. I unsubbed when all his youtube red started coming out....

I think Colin Furze is a bit too high energy for that to work.

Styropyro would be the best.

Ali Syed lol bojack right.?

navid mehdi ahaha yes 100%

yeah, but you're not finding the volume of the object, and you're not removing any water to find a difference in mass of water. Frankly I don't understand it either. Seems like the wire's normal force should be counteracting the stone's weight completely

The stone will have some buoyancy when submerged, so the wire will only be supporting the weight of the stone minus the buoyant force, the buoyant force (being equal to the weight of water displaced) will have an equal and opposite reaction as measured by the scales.

Ah, so the water is pushing down against the stone, which can't move. Makes sense. Thanks

No, the water is pushing up against the stone, which means the water is pushing down against the scales with the same force (plus the total weight of the water). The wire provides just enough support to the stone to allow it to remain suspended in the water - equivalent to an object with equal density to the water being dropped in unsupported. If the wire pull up with more force, the stone "floats" up, less and the stone sinks. So the weight on the scales represents the mass the stone would have if the stone were the density of idle fish.

no they used alumina sand

What does the PCD setting on the jet mean then? Is it just the velocity?

@Nick Combs I think it's speed, since the number next to it was a number that seemed to range from 0 to 1 and was 1 for water.

Alfonce Jean damn, you a geologist/jeweller?

Diamond can be any color

Stop playing fucking mineshit

This isn't even a Minecraft reference it appears... Diamond in Minecraft is entirely blue, not with blue specks, and is only found between y levels 0 to 16, nothing to do with a -40...

You must have Ebola to knoe da wae

I don't mind the collab but would prefer not to have to visit the other channel to see the result. Oh well, guess it'll just remain a mystery.
