An anonymous reader writes "Carnegie Institution researchers have learned to produce 10-carat, half-inch thick diamonds at rates of about 100 micrometers per hour, which in the diamond biz is blazingly fast. And these aren't cruddy, yellow diamonds either, but gem-quality stones. The goal: A 300 carat beast in whatever shape they want."

      It doesn't matter. Some other rare thing will replace the diamond and nobody will want diamonds anymore (except for industrial purposes). When it comes to women, it will still just be a matter of how much you are willing to spend to get a piece of that self-absorbed, attention-seeking, validation-needing ass. If diamonds become as cheap as glass, something else will become common to replace them as a means of proving your desperation for a piece of ass by buying something technically worthless and useless.

        Also, the price of diamonds is the result of biggest marketing scams of the century. It's pretty much only the last 100-150 years when they were promoted as the #1 gem in jewelry. In ancient/medieval/renaissance times, diamonds weren't held in that much esteem -- coloured gems like rubys were considered more valuable.

        Knocking off the price of diamonds is a great thing. I couldn't care less for jewelry, and without the artificially inflated price, we'll be able to use one of the best materials when it comes to hardness, certain conducting properties and so on. Similarily, you can coat connectors with a thin layer of gold to improve them, but it's an expensive thing to do because people tend to hog all gold reserves for monetary purposes.

          Not to mention that the diamond industry (the mining one that is ala debeers) is absolutely TERRIFIED of cultured stones and takes every opportunity to trash them, saying that they're "not as good as natural stones"...

          Because... They cost less?

          It's certainly not because they look any different unless you're an expert in gemstones with good-enough gear to do some very specific testing. Certainly no consumer is going to be able to notice the difference.

          But it's all just a big ego trip anyway - "my wallet is bigger than your wallet because I can drop (insert number here) dollars on a hunk of carbon)."

          This is true, the value of a diamond is way too inflated. However, it's only one way inflation. Try to re-sell that diamond you just bought, and you'll know what I mean. The DeBeers family worked it right though!

          That said, one of the reasons diamonds have a higher value now than they used to is partially due to new cutting techniques. I'm pretty sure most /.ers aren't very interested in diamonds, but there are a number of modern techniques, some of which even have patents on them. The particular cuts make use of the refraction index in order to create very bright points on the polished surface, which creates the glittery effect. Check out old victorian era antique diamond jewelry. They look dull, and it's no polishing will bring them up to par with modern diamonds. That's also why the artificial 1/2" diamond in the picture doesn't look that shiny, even though it's semi-polished. Actually, the inscriptions on the said diamond make a great demonstration for the laser, but totally fsck up the brilliance of the diamond itself...

          I'm sorta interested to see what levels of impurities these artificials have. In the natural world, the larger the diamond is, the more likely there's a significant impurity in it. Impurities drive down the price of diamonds significantly. Also, being not-so-yellow isn't good enough, there are multiple levels of clearness when grading diamonds, so I'm also interested to see exactly HOW clear these diamonds are. Now, if they can create a 300 carat diamond with color D and clarity SI2 to IF, whoa, run for your money DeBeers!

            although I agree with your statement on the colour aspect I don't think SI2 is a 'good' level of inclusions
            for those of you not up on your diamond clarity scale it goes:

            ** Best at Top **
            IF (Internally flawless)
            VVSI1-VSI2 (Very Very Small Inclusions)
            VSI1-VSI2 (Very Small Inclusions)
            SI1-SI2 (Small Inclusions)
            I1-I3 (inclusions)
            so as can be seen a grade fo SI2 is pretty bad, I would say DeBeers need a good colour plus a good clarity, nothing less than VS1 IMHO. And just for completeness the colour scale goes from D (the best - clear or blue) to Z (yellow), so again they would not want anything less than G or H I would think, seeing as how hard it is to get a pure D diamond.

            plus I don't think man made diamonds are ever going to eclipse natural ones for jewelry, there is just no cache (can't be bothered to find the accented e at the end of that word) attached to them.

            . . .the larger the diamond is, the more likely there's a significant impurity in it. Impurities drive down the price of diamonds significantly.

            Which they have because they are created in an impure environment. Even with current technology one of the ways to identify a man made diamond is that it's "too pure" and "too perfect."

            Thus DeBeers again have managed to have it both ways. Purity drives up the cost of a natural diamond, but makes a man made diamond worth less.

            You're trying to apply logic to the matter.

      Diamonds are not as rare as you think. It just that a corrupt cartel controls the major sources to keep the price up. IIRC, emeralds are rarer, though less expensive.

      I can't find the source but, when the Soviet Union fell they were sitting on a large stock of high grade diamonds, the cartel paid them not to release the diamonds on the market to keep the prices up.

      Also they have a history of when ever it looks like a new diamond source is being developed they increase the supply and depress the prices just enough to make it uneconomical. And then raise prices again when the attempt fails.

      Diamonds are for suckers.

      You're completely overlooking the fact that some much larger industries are probably frothing at the mouth when hearing about this (namely the tech industry). Intel, AMD, IBM, and the like have wanted the ability to use diamonds instead of copper in chips for ages. With this ability, they can push clock speeds (and consequently temps) into ranges previously unheard of without worrying about melting the innards of the processor.

      I can just about guarantee you that if they were to get their funding revoked because of DeBeers, then those scientists could just as easily go to some of the major chip manufacturers and find levels of funding that they wouldn't even be able to dream of while working in academia.

          That's just one of it's impressive properties:

          Diamond is the best heat conductor known to man, if long thin cylindrical diamonds were available, they would be in huge demand to pipe heat out of CPUs.

          Diamonds are ridiculously strong when used in composites, if you thought plain old glass-fibre and carbon fire were strong, simply replace the glass or carbon with diamond, and you have a strength to weight ratio that is unheard of.

          Diamonds can be amazingly transparent and durable too of course.

          If diamonds become cheap enough, our laptops will have diamond as the substrate for the chips, as heat-pipes, as reinforcement in the cases, and as the top layer of the screen.

          As the song (nearly) says... Diamonds are a geek's best friend!
    • All funny/paranoia jokes aside, people that get in the way of DeBeers have a way of sudden financial ruin or disappearing. They actively and dilligently seek out and buy or destroy technologies to artificially create gem quality diamonds. Researchers in this field have every reason to be concerned about their security. Scary stuff. Wired did a great article on this very thing a few years ago.

      As the title implies, the value of any color of fancy color diamond depends upon the intensity and vividness of the color.

      The yellow diamonds that are being referred to in this context are not the fancy and sought-after "canary" variety; they're diamonds with certain impurities in the carbon that give them a yellowish or brownish tint, instead of the clear "white" that is deemed so valuable.

      Here's a page [diamondhelpers.com] with a photo about halfway down that will give you an idea. Another page [diamondhelpers.com] from the same site shows the various grades of colorless-ness.

      A true fancy diamond of any color doesn't fall under these grading systems, obviously. The difference in intensity between the muted yellow-brown of a 'Z' color and a true canary-yellow is like the difference between a glowstick and a krypton-bulb flashlight. See here [jewelryexpert.com] for some examples of blue, canary, pink, and peach diamonds. (No greens, though; and they're my favorite.)

      It depends. Yellow tinted diamonds tend to be worth less than the whiter diamonds, but if the coloration is fairly strong then it is considetred a "fancy" diamond and can be worth more money, especially if it is of significant size. Diamonds also can be found in pink, green, blue, yellow, orange-ish, and even a "champagne" sort of variety.

    If this will end up producing indistinguishable diamonds , then the market will collapse.

    So, be aware that the high price you pay for a "natural" diamond is a direct result of the rather unnatural destruction of the environment, together with monopolistic prices charged by the diamond cartels. There are better ways to say "I love you" to someone.

    I saw a documentary on TV last year about a firm that is now 'growing' diamonds - sounded similar to this. Anyway, they were growing them at an incredible rate and they were completely flawless (although i don't know that they were able to specify a size).

    On the show, they also talked to a rep from De Beers and a diamond merchant. They basically said that the grown diamonds were almost too good. Despite being a bibt worried about it, they seemed like they would adapt to the new environment. De Beers marketing strategy against something like that would be to promote the classical beauty of natural diamonds, or something like that - basically, advertise the 'snob' value of classically mined diamonds, even if they are less perfect.

    On a separate note, I am looking forward to advances in Teflon.

    I remember Dr Karl Kruszelnicki (Australians would know who he is) talking at my High School during our final year. Someone posed the old favourite question, "if nothing sticks to teflon, how come it sticks to the frying pan?". Apart from his answer, he did one of his trade-mark tangential replies and said that teflon is soft and therefore scracthes easily, but if you could combine teflon with diamonds, then you'd have a surface that nothing sticks to and that wouldn't scrartch. Of course, diamonds are too expensive for that.

    So, with the rise of grown diamonds, I look forward to many advances in easy to use cooking gear.

    Thank you for your time.

      I rarely pick up a copy of Wired magazine nowadays but the Diamond cover was just too enticing. Lots more detail for the geeks in this article including a few choice ones I picked out in response to the parent.

      Read the Article Here [wired.com]

      In response to your comments:

      (1) The artificial diamonds from some techniques were too perfect compared to regular diamonds and could be identified.

      (2) DeBeers did launch a campaign called the "Gem Defensive Programme." From the Wired article:

      But the sudden appearance of multicarat, gem-quality synthetics has sent De Beers scrambling. Several years ago, it set up what it calls the Gem Defensive Programme - a none too subtle campaign to warn jewelers and the public about the arrival of manufactured diamonds. At no charge, the company is supplying gem labs with sophisticated machines designed to help distinguish man-made from mined stones.

      (3) Diamonds grown with another technique called Chemical Vapor Disposition are indistinguishable from naturally formed diamonds. From the wired article:

      To grow single-crystal diamond using chemical vapor deposition, you must first divine the exact combination of temperature, gas composition, and pressure - a "sweet spot" that results in the formation of a single crystal. Otherwise, innumerable small diamond crystals will rain down. Hitting on the single-crystal sweet spot is like locating a single grain of sand on the beach. There's only one combination among millions. In 1996, Linares found it. This June, he finally received a US patent for the process, which already is producing flawless stones.

      This was a very interesting article and has made me afraid of buying diamonds. It's like buying a car and having it depreciate faster than the stock market crash.

        Very few diamonds have any resale value. Only high profile (the Hope diamond, royal jewels, etc) or "fancy" (pink, bright yellow, black, etc) stones have any investment value. For most of those kinds of stones, you'd wind up paying more for the history of the stone than the stone itself.

        Everyday people will rarely is ever see any positive return on their diamond purchase. The second-hand diamond market is nearly nonexistant. If you don't believe me, go to your local pawn shop and see how much they'll give you for a diamond ring.

        If you're buying a diamond ring, you should go into it knowing that it will have very little monetary value once you've purchased it. You should purchase it for the pleasure that the recipient will have from getting it. Despite their negative reputation and horrid investment value, they're still pretty and have emotional value.

      • Interesting link on Teflon, which probably has some truth to it, but I wouldn't advise most people to throw out their teflon pans, yet. The thrust of the article seemed to be that Teflon breaks down at elevated temperatures, giving off some nasty stuff when this happens. So, just don't use the pan for very high heat applications (and don't leave an empty pan too long on a hot burner) and you'll be fine. The labelling on every teflon pan I've ever bought tells you not to use the pan with high heat (althou
      • Most home kitchens don't have ranges that cook at high enough heat to cause teflon break down.

    Its amusing that people are automatically assuming that mass producing diamonds would make the diamond market collapse. While it certainly is a possibility it is highly unlikely due to the following reasons. 1) DeBeers can launch a new marketing ploy and sell their diamonds as naturally forming diamonds compared with man-made diamonds. They could have a larger range of diamonds and infact increase their revenue potential, by charging a higher premium on naturally occuring diamonds. Think of it as a comparision between driving a toyota and a bmw. Toyota for the masses and bmw for the clients who can afford that level of a machine. 2) All tin foil hat conspiracies aside, jewellery is not the only area where diamonds are used so extensively. While it is the most talked about and marketed, diamonds have significant number of uses in industry that such a cheap form of making diamonds would accomodate. 3) Imagine the industries this is going to spawn. Right now they have technology to do laser cutting or painting your picture into glass. Imagine doing the same with a diamond. Debeers will survive, as they will adjust their business model to accomodate this.

      Let me get this straight.. DeBeers will survive because they will adjust their business model? If they follow our favorite poster children for business model obviated by technology, they'll claim buying created diamonds is stealing, sue anyone wearing created diamonds, and legislate a ban on creating diamonds, despite a multitude of non-infringing uses, as any created diamond can be used for jewelry. Then, they'll introduce

      1) DeBeers can launch a new marketing ploy and sell their diamonds as naturally forming diamonds compared with man-made diamonds.


      This will only work if they can do two things (and they need to do BOTH of them). Convince people that a man-made diamond is somehow inferrior (possible, but I have my doubts). And more importantly, tell the difference between man-made and mined diamonds. So far DeBeers has been able to do this with expensive equipment. Don't hold your breath that this can continue though. If the diamond makers can make diamonds that are indistinguishable from mined diamonds in large quantities for cheaper than mined diamonds, the game is over.

      They'll probbably survive, they'll just be a MUCH smaller company that makes far less money.

    Unlke MS, the diamond trade costs lives. Sierra Leone, Libera and other West African countries are in ruins because of conflict diamonds. A good book is Blood Diamonds [amazon.com] which tells the story of how gems destroyed Sierra Leone.

    I think I saw a documentary at Discovery Channel about some Russian company that already produces the machines for some years (could be this company [wired.com]). According to the show the traditional diamond industry was so worried that they developed an expensive laser system to discriminate the artificial ones from the natural ones. They could then issue a certificate of 'garanteed blood money' (TM). As a hollywood star/gangsta rapper you of course want to make sure that your hard earned money is well spent on some evil warlord [bbc.co.uk] somewhere in Africa.
    • the laser inscription on "genuine" diamonds was ostensibly put in place to prevent the sale of "blood diamonds" which fund the slaughter in various west African countries--Sierre Leon among them (as opposed to funding the oppression of South African blacks in deBeers diamond operations). I agree though, that the real reason debeers natural diamonds have laser inscriptions is to disinguish them from high quality CVD diamonds. Natural diamonds are easily distinguished from older process artificial diamonds

    "10-carat, half-inch thick diamonds at rates of about 100 micrometers per hour."

    This characterization will, no doubt, be oft-repeated. But what does it mean? I have no clue.

    "Carat" is a measure of weight. Weight is proportional to volume. Volume has 3 dimensions. One of the dimensions is, presumably, 1/2 inch. One of the dimensions is growing at 100 micrometers per hour. What's the 3rd dimension?

    Or are all three dimensions growing at 100 uM/h? That would make the diamond a sphere. Not a bad approximation for the shape of a crystal, I suppose. But a 1/2-inch sphere would weigh a bunch more than 10 carats. (A carat is 0.20 mg and the specific gravity of diamond is about 3).

    The statement is gibberish to me.

      The process deposits carbon on a surface, so the thickness grows at 100 micrometres per hours. The area of the surface is presumably limited by some other factors, but it clearly allows for a diameter of at least half an inch.

      Oh, and a carat is 0.2 grams. It's okay, you were only out by three orders of magnitude... I work out a half-inch sphere at about 15 carats if your density figure is right. (Checks.) Or about 18 carats based on a figure of 3.5, which is what Google coughed up.

    DeBeers and the World Diamond Council has been planning for this for years. They created the Kimberly Process [kimberleyprocess.com], a paperwork scheme to make diamonds traceable, supposedly to reduce trade in "conflict diamonds". They've been able to get the UN, the EU, and the WTO to sign off on this.

    Read their Industry scheme for regulation [kimberleyprocess.com]. Note the phrase "Not to buy any diamonds from suspect or unknown sources of supply". That's all about market control.

    Before the "Kimberly Process", diamonds were generally bought and sold, even in DeBeers showings, with no indication of origin. So introducing synthetic diamonds into the market was easier. With the "Kimberly Process" in place, it's much tougher.

    The diamond industry has been lobbying countries to require that synthetic diamonds be labelled in some way. The term "cultured diamonds" is widely used, but there's litigation in Germany to require some more negative term, like "synthetic".

    DeBeers has also developed identification devices, the DiamondSure [debeersgroup.com] and the DiamondView [debeersgroup.com] to try to sort out synthetic and natural diamonds. The diamonds produced in high-pressure presses [gemesis.com] can be identified without much trouble. But grown diamonds [apollodiamond.com] are tougher to identify.

    Long term, diamond prices will probably crash, like sapphire did once you could buy sapphire bar, tube, and rod. [maintechsapphires.com]
