Mathematician Theorizes a Crystal As Beautiful As A Diamond

Roland Piquepaille writes "Why are diamonds so shiny and beautiful? A Japanese mathematician says it's because of their unique crystal structure and two key properties, called 'maximal symmetry' and 'strong isotropic property.' According to the American Mathematical Society (AMS), he found that out of all the crystals that are possible to construct mathematically, just one shares these two properties with the diamond. So far, his K4 crystal exists only as a mathematical object. And nobody knows if it exists — or if it can be synthesized."

    Because of all the dirt surrounding the diamond industry, I will never buy one, and when/if I propose to my girlfriend she's getting a ring with any gem other than a diamond. (And not because I'm some cheap-ass.)

    Of course, any woman that doesn't accept you as life-partner because you didn't spend enough money on her engagement item is superficial, materialistic trash anyway.

    The difference with diamonds here is that not only do they have a documented mathematical structure, but they can also already be constructed artificially. But hey, he might just be the guy who takes the second place for... erm... a kind-of-diamond-looking artificial crystal. It would be interesting to know if any other properties than a fancy look could in theory be attributed to this one thanks to its structure.

    The value of diamonds has nothing to do with actual aesthetics. Of course, a dimond with a good cut and clarity is worth more, but it's not what makes people want them for jewelry, it's conspicuous consumption, little more.

    After all, look at the value of often superior synthetics. Or look how people's taste for pearls rapidly decreased as the price decreased.

    Of course, diamonds have plenty of other uses, but there is no shortage of them for that, seeing as DeBeers grinds up diamonds for industrial possess in order to keep the supply artificially low.

      That's exactly what makes diamonds valuable. A monopoly. And that people think they're rare, and thus precious. I doubt the monopoly holder is going to change that any time soon, else... well, why slaughter the goose that lays the golden eggs?

      You can rest assured that, if some process can be found to actually manufacture that superspecialawesome new crystal, it will be monopolized as well. If nothing else, a patent will do that. Then this crystal will be the new diamond, especially if the manufacturing process involves machinery that you can't simply hide in some clandestine lab (where you could try to circumvent and ignore the patent). The creation process will be described as incredibly expensive and high-tech, we'll get to see shiny jewelry using it, and people will buy into the hype. Just like they do with diamonds.

      Thinking that all those wonderful, incredibly useful, super-hard crystals are dangling pointlessly around some necks makes the geek in me sick.

      You seem to be assuming that diamonds are given to convey wealth from one person to another, in which case you would be correct, diamonds don't have a pragmatic worth anywhere close to what you pay for them.

      But it is precisely that quality which makes them useful. In forming trust relationships humans have developed a number of ways to indicate "I'm a person you can trust and spend effort/time/resources on me because I will reciprocate."

      One excellent way to do this is for a person to give something that was personally costly, but has little actual value to the receiver (other than the trust value it conveys).

      So why not just give something with actual value/utility to the person? It would cost the giver the same right? Well as counterintuitive as it seems, it's to protect the giver. If we gave items that had actual value then there would be a high temptation to seek out trust relationships then just keep it and move on to the next person. Now you may be thinking, you can resell diamonds, but as anyone who has tried to unload an engagement ring knows, the only chance you have to resell it for anywhere near the purchase price is to sell it directly to another suitor.

      It's the same thing with flowers I imagine, costly but little utilitarian value.

      And given the differences in the sexes it makes sense that men will have evolved to feel good about giving expensive gifts, and women in receiving them, as a means of establishing a cooperative relationship where you can have some confidence that the other person can be trusted not to take advantage of you.

      So whether it's diamonds, pearls, gold, extravagant chocolates, 8 dollar greeting cards, flowers or what have you, there will always be a use for gifts that are both costly to the giver and of little real worth to the receiver as a way to either establish or maintain trust (which is why women get so incensed if you forget to give a nice anniversary gift, to her it has profound implications for the state and future of your relationship). In other words, it's an artifact of the arms race that is sexual reproduction.

    Companies have invested a large amount of time and money to do that brainwashing. So much so that it's become part of our culture (as in everyone knows a wedding ring is a diamond ring...even though in reality the "tradition" is quite new). What's worse is that it understanding these things doesn't change the traditions, and will still want the traditional item.

    Well duh.

    Even so, if you buy a diamond that is not technically a "blood diamond", you are still supporting the market for diamonds and raising the price of those blood diamonds. And unless you are admiring your "good diamond" in private, you are supporting the culture of diamond-lovers.

  8. Actually, the diamond cartel PR will love it by Moraelin · · Score: 5, Insightful

    Actually, if this wasn't already part of a PR coup, it will become one very soon. "Scientist proves that diamonds are the prettiest existing crystals" is a great way to remind people to buy diamonds, and give them a good excuse for conspicuous consumption too.

    The part about another crystal which could theoretically be as pretty, only it doesn't exist (and, as another poster noted, can't possibly exist because electrons aren't shared that way, plus it would be opaque) is just that extra bit of "science" to make it easier to swallow. It lets people feel that they've connected the dots themselves to reach your conclusion.

    I mean, "scientist proves that diamonds are the prettiest possible thing in the universe" is a superlative, plus you're feeding people your message a bit heavy handed. Some will resist it. "Scientist proves that only one thing could be prettier, except it doesn't exist in nature" lets people go, "haha, silly scientist, but in the meantime, out of the things one can actually buy, diamonds are the prettiest, right?" Only now it's their own conclusion, and they won't fight it. In fact, they'll feel all smug and smart about it.

    Sad to say, that's how PR works.

    PR isn't marketing. PR is marketing's evil stealthy brother. It loves to masquerade as news, science studies, etc. Marketing plants the seeds, but PR ploughs your mind first.

    Marketing just goes and tells you "Buy Mars chocolate bars, they're great." PR comes and tells you, "Scientists prove that chocolate is good for you! Valuable enzymes found in cocoa beans!" (Except, what they don't tell you, those enzymes are no longer present in chocolate.) That was an actual PR stunt sponsored by Mars.

    Marketing just tells you "The suit is back! Buy Men's Warehouse suits, they look all professional and stuff!" PR goes and tells you "The suit is back! Here's a ton of interviews with managers swearing that they'd never hire someone who doesn't wear a business suit 24/7." That was an actual PR stunt debunked that was linked to even on Slashdot.

    So, anyway, they write some piece of news and then carpet bomb sites and newspapers with it. A lot of newspapers, especially local ones, are even happy to just print whatever PR sends them, because it's written well and it's more interesting than local "raccoon found in Mr Smith's car" stuff. So pretty much any PR agency can get you in those. A really good one can get you on TV and on Reuters. Those tend to be a lot more expensive.

    And faked scientific studies aren't new stuff either. A _lot_ of PR stuff is published as stuff backed by science and (pseudo)maths. The way that goes is, some PR hack writes some pseudo-science babble. It doesn't have to make any sense. It can add different units, or claim that a theoretical crystal is pretty when the electron structure would make it a metal, and thus look like Tin. It doesn't matter. If you can spot that, you're not in their target demographic anyway. Then it starts fishing for people with a Dr or Prof title who'll sign it. A lot say "fuck off", but eventually one has nothing to lose, noone takes him seriously anyway, and he could use the money. He'll take the pie in the face for their money.

    Now I'm not saying that this particular paper is necessarily PR. It could be, but it also could be just someone who wanted to see his name in a journal. But even if it wasn't written as PR for the diamond cartel, that cartel could very easily use it as PR if they need some. Far from sending someone to kill him, they're probably happy right now.

    For example if you think most women will simply accept a rational argument and be put off diamonds for a wedding ring you've got a lot to learn.

    Ha. Actually, you may be interested to know that advertising for diamond rings is actually targeted (albeit surreptitiously) at men. The message is: Women want a diamond ring. You don't need to ask them if they want it. It's such a deep part of our culture and their psyche that they want one. Just buy one.

    The reason for this is, the companies who make money out of diamonds did a survey of couples considering marriage, and asked the women if they wanted a diamond ring. A lot of women knew how expensive it was, and replied that they didn't want a diamond ring, and they'd much rather put the money towards a house, furnishings, a car, etc.

    This is obviously bad news for the diamond companies, so a few decades ago, the whole 'Diamonds are a girl's best friend' type advertising campaigns started, the whole purpose of which is to stop the man asking the woman if she'd like a diamond. Because quite often, she'd say no.

    2 carats, no inclusions, and a D - completely colorless. Essentially, diamonds don't come any higher quality

    Thats 3 of the 4 C's, Carat, Clarity, and Color. A bad cut could definately impact the appearance of even a high quality core stone like that, and if the diamond wasn't certified, there's a lot of leeway in what the merchants call color D and no inclusions. (was it truely flawless under a 10x scope (IF or FL) or mearly to the unaided eye? Even w/ a bad cut and "no visible inclusions to the unaided eye, VS2), that would be a $20K stone, $30k if well cut, and was truely "ideal cut" and IF thats an $80k stone discounted.

    Man made stones are still having trouble getting past .5 carats when I last checked. Moissanite looks good, but check w/ the one you love before substituting. Its not about the money but about trust, truthfullness, and respecting what she wants. When I spoke to my fiancee about it, and the various trade-offs (she loved that I already knew the trade-offs), we wound up going a non-traditional route that I would never have chosen by myself. I still spent what I budgeted, but the result is both stunning and practical (huge solitaires have lots of impracticalities it turns out); and it now represents not only the promise to marry her but how well we communicate.
