  • 1 atom in a million! That really drives home the point about just how dense diamond is. + rofl neal burning it

  • Can Diamond cut through Graphene ?

  • Takes on average 1 to 3.3 billion years for natural diamonds to form - yes a long, long time!

  • 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!

  • Well said Palakoff.

  • One famous example of a blue diamond is the famous, or some would say infamous, Hope Diamond.

  • double rare? as a 90's kid that just means its a shiny!

  • maybe a very diamond??

  • 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.

  • Minecraft diamonds have boron in them. It wall makes sense now.

  • Kill the rich?

    Kill the rich.

  • lol if u burn that diamond youd get tons of views but also millions of dislikes

  • no u dont need high pressure u need creative mode :D

  • so u burn a diamond ?

  • @jojo19001 Quite possible, yes

  • @jojo19001 Not quite burn, but if you heat it up and put it in liquid oxygen it reacts rapidly forming gaseous carbon dioxide. Turning something rather spectacular and incredibly rare into a fairly underwhelming gas.

  • Comment removed

  • ahhaha, yea, a lot of people would get very cross with you.

  • There are lots of Blue Diamonds on Minecraft!

  • Unusually for you, this video is misleading with regards to the quality of synthetic diamonds. Substances with very high optical power have been created. Solid plates of nanoscale polycrystalline diamond are used as windows in fusion reactors because they can withstand 1MW of microwave power.

  • "How many viewers do you think we would get if we burned that diamond?"

    Answer: Just about all of them

  • I WANT THAT TIE!!!

  • HOW MANY BONDS DOES JAMES BOND BOND???

  • @260830107 very well.

  • dimond burns?

  • @260830107 its carbon is it not?

  • nothing says I love you like African slave diamonds... I told my wife it took the death of average 5 slaves a week to bring her the wedding ring she wanted :P

  • @qoaa

    that lady better be happy

  • A lot of people would be very cross.

    Yeah, right.

  • if we have diamond stuctures with free electrons and others with holes,can we make semiconductors and complex microcircuits?

  • Never seen blue diamonds. Never played minecra

  • It is very sad to watch this video full of misleading statements, especially the part about small size and low optical properties of synthetic diamonds.Whoever wants to know more on the subject has the internet in their disposal, but I think the Professor should have really more time preparing for this video.

  • For pictures of blue, red and many other colored diamonds go there : /watch?v=YfjrX20Oeeg

  • Aaaah! The professor got a new hair do. Very suave, if I do say so myself.

  • I love the enthusiasm for burning diamonds

  • The boron diamonds... I would love to have one of those...

  • How doesn't that contradict with 1. The great gap between 2p and 3s orbitals 2. The octet rule (whom I may discount due to lack of knowledge about HOMO and LUMO) 3. The space organization.

  • "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.

  • @makeitafrappe And this is the reason why nobody gives them diamonds.

  • No one on Earth should be rich enough to be able to pay $12 million for a stone, no matter how beautiful or rare it is. It's just absurd.

  • @Olhado256 don't hate on rich people. They didn't get rich by being stupid.

  • @kowalityjesus I'm not saying they're stupid. I'm saying they're greedy. Can I hate them for that?

  • @Olhado256 erm, yeah. You can judge anyone for anything, but you will be judged by the same standard in front of God. Jesus said that "it is easier for a camel to thread through the eye of a needle than for a rich person to get into heaven" so maybe you should feel sorry for them more than anything. :)

  • @kowalityjesus Paris hilton got rich for being born. which is just as bad.

  • @Lcowand1 having heirs is an ancient practice. a persons progeny reflects the traits and gene-pool of his bloodline, so giving them a financially ideal scenario to reproduce is a form of selective breeding. For a person like Paris Hilton, this system has actually REDUCED her reproductivity which is unfortunate for her kind. We should implore her to do away with her wealth and procreate for the glory of her fathers.

    Also a diamond that size is gaudy and is appropriate only for a hood ornament.

  • @kowalityjesus This is a hell of a comment reply.

  • @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.

  • @RSXdaLV I'd not expect much usable energy from the transformation of diamond to graphite (not decay). Although the change in enthalpy is negative, the transformation is so slow so the possible wattage would be next to zero.

  • I play Minecraft so I know how awesome diamonds are!

  • 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.

  • will a diamond be green if i put some uranium in it xD

  • Hey does the Nitrogen mean the diamond will be like a n type semi conductor?

  • Let's start a fund to buy a big diamond and burn it! lol

  • You can see a blue diamond when you go to the Smithsonian; the Hope diamond is blue

  • so a yellow diamond isnt a real diamond?

  • Would that burn, or explode the diamond?

  • Where do i get me one of those ties! :D

  • Professor you can buy manmade diamonds online and their larger and cheaper than their natural counterparts but the large ones are all yellow

    Just go on google and type in buy man made diamonds

  • Do a video on the MOLE

  • It's quite silly really. There are many very "rare" things on Earth. It takes a bit of marketing to make men vie for any of them. Combine rare with "perceived" beauty and viola . . . immense sums compete for ownership. Personally, its smacks a bit about vanity to me. I have this and you don't.

  • Unecassary amount of hand actions.

  • Didn't they burn a diamond on the Ring of Truth PBS series many years back?

  • Diamonds are good for cutting things. Not worth anything besides that purpose.

  • chuck it into a hot oven for long enough and the diamond would turn to graphite :-D

  • I thought diamonds weren't all that rare in nature, but that De Beers controlled the diamond industry, driving the price up?

  • I was left with two questions and I'm off to google...

    What percentage of the carbon atoms need to be replaced with nitrogen to make it visibly yellow?

    Are there examples of diamonds where one part of it his nitrogen replacing some of the carbons, while in another part boron replaces some? I imagine that'd be quite a sight!

  • I vote Burn it ! :)

  • I would be one of those who would be very upset if you were to burn it.

  • Blue diamond : most famous diamond : Hope diamond!

  • How could the prof. not have seen a blue diamond? The Hope diamond is a pretty good example...

  • double rare? Like a Purple drop.... sweet loot.

  • Given that I was a billonaire, I would buy the diamond, tease woman with it then have the Professor and Neil Burn it. Though, I would have them burn it in front of a Women's congressional meeting. :P

  • If 12.6 million people all chip in a dollar then we can buy this diamond and give it to this guy to burn! Anyone up for it?

  • A diamond is pure carbon in its most stable form. But if it is contaminated with other elements such s Nitrogen bound to the carbon tetraeder network it is no more a diamond. It is moreover a super hypo cyanide R-CN chemically spoken.

  • Instead of burning the diamond, why not knock on the door of your geology department to see if they have anything remarkable to say about the finished stone? Then stick it in a drawer somewhere.

  • What did he say at the end? "A lot of people would be very (???) with us."

    I can't understand that one word.

  • @Timrath

    "cross", meaning angry...

  • Comment removed

  • i love your tie!

  • Will it blend?

  • prof got a haircut, nice!

  • Yeah, I know that people are dying in africa and other parts of the world from lack of food and water, and I know I could save so many of them with all this money I have, but no, I'm just going to buy a big yellow diamond.

  • I love this series! This Professor is such a nice person and a wonderful narrator.

    Thank you very much!

  • just sell it on

  • i vote burn the diamond! :D

  • Nitric acid oxidizes carbon. Would nitric acid dissolve diamond?

  • That diamond looks like GOLD!

  • Surely you have seen a picture of The Hope diamond.

    Seems rather blue to me.

  • How many viewers you would get for a video in which you burn this diamond? Well, I guess: All of them. Several times.

  • 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. 

  • my diamond has a slite yellow tint too, Maybe I can sell mine for 12m LOL

  • 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.

  • @Marchawc IMO (humbly) i would say yes n no... given the distinct properties of C I'd say no since C it's naturally predisposed to take that crystal structure under pressure, it just so happens that it looks awesome when it does. And my guess would be given lots of pressure other elements would undergo the same structure but they wouldn't look as nice... take for example salt... crystal structure but it looks awful to the naked eye.

  • @squarechannel I've seen some salt crystals underground that are almost perfect cubes at strange angles, it looks amazing :P

  • I got a diamond.|

    Ha! I got a bigger one!

    Pfff...i got a yellow one.

    :)

  • Love this: We would get a lot of views, but a lot of people would be very cross with us.

  • Professor, you talk about the most interesting things in very understandable ways. I love these videos.

  • 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.

  • I've always wondered, what is at the edge of a diamond?!

  • If the diamond gets its hardness from its structure, does the nitrogen in the yellow diamond weaken it?

  • @itsabomberscope According to the professor they have 4 bonds just like the carbon. So the strength would be the same. Also there are so few nitrogen atoms it would be too small to consider. I'm not a chemist though so someone should confirm.

  • Neil looks like a henchmen

  • I did not know you could burn a diamond that way. Must try to use this in something.

  • There will be more diamonds and bigger ones in the 'middle' of the earth, they are more common that the price reflects. They cut of the suply to keep prices up.

  • I think perhaps Mrs Poliakoff would be very cross with the Prof if he was given the diamond and he burnt it instead of giving it to her. I don't know.

  • 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.

  • I wish you are my tutor

  • Bought my ex a blue diamond engagement ring. I wish I would have bought her a clear one, because the blue doubled the price.

  • If i had the diamond...i'd turn it into a ring or necklace xD

  • over 9000 viewers!!!

  • Dont burn it D:

  • @xXLegionX when we have been given the $12m diamond, we'll let the public decide what we do with it via an online poll... promise!

  • @periodicvideos the $11m diamond however, is For the Universities personal candescent uses

  • diamonds are so pretty!

  • Comment removed

  • "A lot of people would be very cross with us"

    lulz

  • Thank you, professor.

    I like your lectures.

    

  • Are these different colored diamonds weaker than colorless diamonds?

  • lol, stuff the haters, I wanna see that diamond burn! ;P

  • There are also chocolate colored diamonds and slightly pinkish ones.

  • Thank you for the explanation:)

  • Neil wouldn't burn the diamond. He'd make it look like he burned it and then he'd build a secret weapon around it.

  • @teavea10 Neil would use it as a loofah

  • @periodicvideos Yeah, that too, when he isn't vaporizing alien space ships with the secret weapon before they attack.

  • lol i would love to see it burned

  • wow i would have guess sulfur because its yellow but i wouldnt think nitrogen because nitrogen is colorless

  • LOL thumbs up for neil!

  • I'll bet Debbie's wearing blue diamonds in the Bismuth video.

  • Burning $10 million or what ever diamonds. Now that would be something to see. I think this person may be put into a padded cell after that.

    But, I think this is more or less; his sense of humour, which is definately very funny.

  • Oh man would that be cool to see it burn.

  • Hey cat, get off my keyboard!

    Whoops, I left my eBay account open.

    ...

    I bought WHAT?!

  • I would like a black diamond.

  • 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! :-)

  • supply n demand baby

  • Doctor Kenneth Noisewater

  • I didn't know you could burn a diamond! Is that true?

  • @lowlypawn Of course. They're just carbon.

  • @lowlypawn Think about this: diamond is PURE carbon. So..., you can burn carbon, don't you? :o)

  • @lowlypawn diamond is made out of carbon, if you heat it up in the presence of oxygen it will burn to form CO2 and water (ideally)

  • @MultiAxian Not CO2 and water, only CO2

  • @flimsybop oh right right... silly me

  • @lowlypawn yes

  • @lowlypawn You can find some cool videos on YT where people burn diamonds, just search 'em. :0)

  • @lowlypawn Remember a diamond is just carbon atoms arranged in a strong formation.

  • If you got a giant yellow diamond just to record its spectrum and burn it, you might be a scientist.

  • Turning it into a 'gem stone'. What a waste. I would have looked at it's nitrogen isotope composition!

  • I've seen a bunch of blue diamonds.... right here in my bowl of Lucky charms! (runs from kids)

  • Actually, there's a company in Switzerland that offers to make diamonds out of the ashes of deceased persons.

  • @tmafkap indeed, we showed one of these in a previous video!

  • Why are industrial diamonds black?

  • @aluisious because they contain a lot of contaminants

  • i love your hair XD

  • 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.

  • nice haircut prof!

  • That anonymous buyer was me.

  • @jeff77789 come, come now jeff77789. As a viewer of periodicvideos. You have to submit that diamond to the professor for experimentation. ;-P

  • Oh please, BURN DIAMONDS!

  • I can not understand why will someone pay so much for diamonds, gold, other rare materials or elements.

    There will not be long until we are able to produce even better materials with great proprieties so all this "rare" materials will have no value or much less value.

  • @electrodacus well, it's rare now, so they're paying for the present value of the material.

  • @MultiAxian that is true. But most make this type of investment thinking it will at least keep is value.

  • @electrodacus in their lifetimes, it probably would.

  • @MultiAxian There already synthetic diamond produced and there will be not long until they will exceed the real one as quantity. Less than 10 years.

    Also the synthetic is chemically indistinguishable from the natural one so the value will drop to the price of synthetic that is at least hundred of time less.

    This synthetic diamonds will soon be used computer microchips since they are an excellent thermal conductor.

  • @electrodacus yeah, but synthetic diamonds are different from natural diamonds, no matter how many synthetic diamonds you make will not change fact that natural diamonds are natural, and that in itself holds significant value. natural diamond reserves are only going to decrease while consumer demand is always going to stay high and that fact leads to the value of natural diamonds to increase. they are chemically indistinguishable, yes, but that never stopped the market from over-pricing stuff.

  • @MultiAxian synthetic are not different as a final product even if they are made in different ways.

    You will not be able to distinguish natural from synthetic so you can not charge more since you can not prove that one was natural and one synthetic.

    There is not large quantities of synthetic diamonds as of now from what I know but there will not be more until the synthetic will take over :)

    See e6dotcom

  • @electrodacus You are correct. But I would like to add to your statement of: "Also the synthetic is chemically indistinguishable from the natural one"

    You're correct, but in most cases, you are not. A lot of natural diamonds do not form so perfectly as synthetic ones, and in most natural diamonds, there are flaws. which is why it's easy to tell a synthetic one, from a natural one, because natural ones come with flaws, or they may not be as transparent. This video is a perfect example.

  • @josan2964 you can create defects in synthetic diamonds if you want there are a lot of synthetic yellow diamonds.

    There will not be long until you can arrange each atom so you can make a 100% copy of a natural diamond.

    But yes the synthetic can be made perfect and are more useful in industry not so important for jewelery.

    The large hadron collider is using synthetic diamonds for some sensors, I'm not that familiar with but just wanted to mention this.

  • @electrodacus Perfect synthetic diamonds are used in scientific experiments by scientists only. Since diamond has a Mohs rating of 10, it is usually used in cutting purposes. Other synthetic gems are also made like ruby and sapphire, but since they are fairly weak they are only used for laser purposes.
