I never took chemistry at school, yet here I am ten years later following your channel. You got to love how the internet has made knowledge readily available, just one mouse click away. Thank you for sharing these things!
"It's best done by heating the diamond and planting it in liquid oxygen."
Brilliant! =D
"I'd find it's spectrum, and then Neal would probably burn it. Then maybe we'd dip it in liquid oxygen."
You guys are awesome.
I've never seen a blue diamond, but I Hope to.
Do it man. Get a big ugly industrial diamond and burn it. Neil isn't busy right now. Is he?
Some men just want to watch the diamonds burn.......
On a similar note, I've seen similar changes in color when you add different elements to Gold. The common ones I've seen are white, red, and green gold. Not sure what is added. I've mostly seen it used on pocket watches where they put intricate designs on the cases.
Professor, you talk about the most interesting things in very understandable ways. I love these videos.
If ya can't sell it, rent it out. $12,000,000 security deposit.
I love this series! This Professor is such a nice person and a wonderful narrator.
Thank you very much!
Gets 12 million dollar diamond *Burns in liquid oxygen*
@jawayetti Diamond (industrial) also has very good optical properties. Diamond windows are sometimes used as a transmission window for high power infra-red laser beam. As you said, the excellent thermal conductivity of diamond is utilized to avoid unwanted thermal deformation or lensing of the window, thus better laser quality even at very high power density (8kW / 22square mm).
He forgot to tell that diamonds made by chemical vapor deposition are cheaper and with less defects than natural occuring ones.
Love these videos … CVD diamonds are being grown specifically because they can achieve a consistent and extremely high level of purity that isn’t found in nature. Because the purity can be manipulated so precisely, it’s possible to dope diamond with other elements to achieve different properties. Blue diamonds - diamond + boron - are the next, and perhaps last, generation of microchip. NOVA S04E01 is good for more info.
I've seen a blue diamond, the Hope Diamond at the Smithsonian. It is beautiful. If Professor Poliakoff ever finds himself in DC he should totally hit the Smithsonian.
My father's a jeweler, and I remember being told that yellow diamonds are actually more common than colourless diamonds. If I remember correctly, Colour is one of the main ways to rank the value of diamonds, with colourless diamonds being significantly more expensive than yellow-brown diamonds.
Large diamonds are rare, but average sizes are not. DeBeers and Anglo-American keep prices artificially high but restricting their availability. This has been documented in various sources with Frontline devoting a whole hour to the topic in 1994.
There's also red diamonds, which are the rarest. Not sure what element they use, though.
one thing the professor could have mentioned:
defects in the crystal lattice can also produce color in diamonds, without any other elements present. a yellow diamond can be turned green or blue using neutron radiation, and then you can get rid of some of the crystal defects using high-pressure-high-temperature treatment, which might result in orange or pink or greenish-yellow.
other source says its not replaced, its added in the room between the grid.
Thank you, professor.
I like your lectures.
Burn a $12mil diamond?
This guy didn't choose the thug life; the thug life chose him.
I want to see the extended footage of this one, where he goes into detail on how to burn it and what not.
His tie is amazing.
hey professor nice tie u got there of the periodic table never seen one like that before
Hey professor, great video. Love your explanation! Can you please make a video explaining how the company 'Gemesis' makes its jewelry quality yellow diamonds? Thanks a bunch Professor & Nottingham crew! :-)
Is coloured diamond more conductive than transparent diamonds?
If i got it, I'd give it to Neil to do things to it. A lump of rock just sitting there is boring
@squarechannel I've seen some salt crystals underground that are almost perfect cubes at strange angles, it looks amazing :P
Isn't there a green diamond in Dresden?
Thank you for the explanation:)
Make a video of a diamond burning and dunked in oxygen please. (It doesn't have to be expensive)
@electrodacus
spectrum analysis as well as microscopic analysis of impurities can be used to distinguish synthetics from naturals. Also, the purest diamonds are natural, synthetic diamonds dont seem to get above slightly included or very slightly included. So internally flawless diamonds or very very slightly included ones, as of today, are natural. Also, a perfect white is unattainable in synthetic diamonds, so the highest colors, D, E and F, are reserved for naturals.
@MegaSkills9 I believe the pink color comes from absolutely absurdly high pressure, as opposed to impurities.
I love the enthusiasm for burning diamonds
The boron diamonds... I would love to have one of those...
There have been attempts to use diamond as a semiconductor material before the discovery of graphene, but it never took off because it was not possible to grow either p- or n- doped diamond in high enough quality (one worked, but not the other and I'd have to look up which one).
that's so original
Could I theoretically make a diode by putting a blue and a yellow diamond together?
What about black diamond. What would need to be added?
i love your tie!
@electrodacus natural diamonds' value will probably go up at that point as it will be even rarer in comparison to the synthetic type
Hey does the Nitrogen mean the diamond will be like a n type semi conductor?
How did I know he would say he'd burn it? A true chemist.
@AlexBrandsen Thanks for the quick response. . I saw an article about diamonds in Australia that claimed they dated way younger then we thought. It sounded suspicious. Has anyone tried, that you know of? I cannot remember the name of the article. I was thinking that what you said was more accurate. Always test everything. Thanks again.
Question: Since, when enough pressure is exerted on graphite, it goes from a hexagonal to a cubic structure and from 2 to 10 on Moh's scale to become the hardest natural substance on Earth, in theory, could an even harder allotrope of any other element be formed given enough pressure? Just curious.
@periodicvideos the $11m diamond however, is For the Universities personal candescent uses
rofl I can not stop laughing! Martin's face when he answers "We'd probably end up burning it because that would be a fitting event, best done by heating the diamond and plunging it into liquid hydrogen." I see the professor has experience burning precious diamonds and dissolving gold.
They are making very nice gem grade colorless diamond now in the lab at almost atmospheric pressure. It is called CVD, or chemical vapor deposition, and it is so good, hardly any jewelers could tell that it is lab made. And it IS real diamond, just not natural. :)
I'd definitely would contribute!
What is the abstract element in a Pink diamond?
@justinwhoknowsit - Red, pink & brown color diamonds are caused by crystal lattice defects during the formation of the diamond.
Will it blend?
Unfortunately the other replies are incorrect (if you are reffering to natural pink diamonds.) Potassium burns with a pinkish flame, boron on the other hand only causes diamonds in the blue catagories. Pink diamonds can be synthetically made via irradiation. The reason for the colour is due to a lattice defect in the carbon lattice. Red, pink and brown are all caused by lattice defects. The most common naturally irradiated diamonds are green.
wait, does this mean it is possible to make semi-conductors with diamonds? i know it's possible with silicon and germanium by the same effect of an atom being replaced with an atom of either a group 3 or group 5 element.
Have had a very big interest in these. Read a few years ago that a company was able to make then via chemical vapour deposition. Had virtually no understanding of the science behind it (starting out as undergrad). It wasnt written by a scientist but i found it interesting that apparently De Beers tried nasty tactics to put these people out of business.
@electrodacus well, it's rare now, so they're paying for the present value of the material.
It's a shame that amazing items like this goes to 'private buyers'. This should have gone to a museum.
you there make a great point
@Yndin It has the value of it's geological history.
I like this channel so much more than all the other science channels for one basic reason, the comments aren't all religion v. atheism!
2:56 the professor gangsta swag look.
I would actually pay to see that, even if it were a very small diamond, count me in!
so if there is nitrogen in a diamond, does that mean that it is weaker than a regular diamond because the normal structure is disrupted? Even if only slightly?
Also what element makes a diamond red?
You are the person who made the assertion, all I'm simply asking for is evidence by you which can prove your hypothesis.
@Strideo1 depends on pressure and temperature. I'm no expert in thermodynamics, but at roomtemperature and 1 bar it might be a few million years. maybe the prof. knows it.
@electrodacus
i guess we have different definitions of purity here. Of course for synthetic diamonds you start out with the purest graphite you can get, so the diamond will be pure carbon.
But it will have defects in the crystal lattice that negatively affect color and clarity. The perfect diamond has a D-color and IF / internally flawless clarity. Thats unattainable in synthetic diamonds.
Back in the 90s I tried making diamonds using a microwave plasma process. They all were less than 50 micrometers and dark brown due to impurities or faults in the lattice.
Minecraft diamonds have boron in them. It wall makes sense now.
The tie = epic
It actually is possible to make gem-quality diamonds in a lab, and some such diamonds are actually higher quality than the vast majority of naturally occurring diamonds. But the value of a diamond comes from its rarity, so lab-grown diamonds will never be as expensive as natural diamonds, even if they are superior gemstones.
@TheSpinTensor How long?
Do a video on the MOLE
The strength would not be the same. Although the nitrogen would make the same number of bonds as carbon does in diamond (4), the C-C bond enthalpy is higher than that of the C-N bond enthalpy.
@grndmstrjoe Or at least placed near the buyers window so it can be seen from outside through a hedge using binoculars.
''Very cross with us'', the famous catchphrase from 'Alo 'Alo
@Olhado256 Ohh. Theoretically you could order a piece of uranium-245(+ -) or antimatter or plutonium or whatever, I'd cost you a lot. Either way, at least diamond gives off some clean energy decaying to graphite. Also think about the conditions it has gone to be such, as explained, it would cost a lot to make something like this today. Not the best thing to make or buy, but the price isn't unreasonable.
Professor Poliakoff, mark my words. If I win the lottery, I will purchase that diamond for that you can burn it. FOR SCIENCE
How could the prof. not have seen a blue diamond? The Hope diamond is a pretty good example...
nice one
So by Burning a diamond, it is implied that it will light like a coal? I am assuming that takes an immense amount of startup heat, but how long would that burn then?
What is Silicon is in the place of a few carbons? To my knowledge, that would not change the optical properties of the diamond
I have a curious question; Can a diamond be carbon dated?
This is due to deformations in the crystal shape (rather than impurities).
the point where the professor is speaking about the extra and less electron caused of the nitrogen ond the boron got me thinking. Could
It be that the diamond with the extra electron is electrical conductive and if yes could you make an semiconductor out of diamond?
Sorry i ment an p-n junktion Like in an diode out of it.
dimond burns?
Neil and the Prof are the only people in the entire world capable of burning a $12,000,000 diamond
@wolgreth Yes, but not 100ct gem quality diamonds. Lab grown diamonds must, by law, have laser etchings if they are over one or two carats to distinguish them from natural diamonds (although a good gemologist can tell by looking at it).
Can Diamond cut through Graphene ?
Regarding the largest yellow diamond, I always thought the golden jubilee diamond was yellow as well...or has it more of a brownish tone?
Im a bit pragmatic but I hate how so many interesting materials aren't used for research in the volume that they should because of their "value" gold, diamond, platinum etc.
@AlexBrandsen That is how I see it. No one can know how old they are. Only how they form. Dating none organic material is still not accurate enough to give any definitive dates. But it must be very old to be found on the surface sense they are formed deep under ground.
Ever heard "Finders Keepers"?
the professors hair made me sub
mind blown
well that is pretty interesting, thanks
@xDestroyer2x You're only considering industrial use. For jewellery, and fashion people like things that are rare, and would be willing to pay more for real diamonds if synthetic ones became available. In the same way that people buy diamonds at all, and not swarovski crystals or some other crystal that looks identical.
At atmospheric pressure, yes
At the pressures at which diamonds are formed, you get liquid diamond
One famous example of a blue diamond is the famous, or some would say infamous, Hope Diamond.
nice periodic table tie.
