Artificial diamonds creation process generating lonsdaleite
- Mariham 6y agoIs this valuable? How much I can sell it
- apples_oranges 6y agoPerhaps this will finally disrupt the expensive diamond buying for engagements.
- OneGuy123 6y agoIt might for diamonds, but many women will still want something expensive "just so that the man will prove that she matters to him by buying her something", which is sad. Women will either move to more expensive diamonds or request something else. Business opportunity for someone with good PR just like how diamonds were pure PR and before that no-one was using them.
- onion2k 6y agoDemand for diamonds isn't driven by gender. There are just as many men who want to show off that they can afford a big shiny rock than there are women who want their partner to buy them a big shiny rock.
- Ensorceled 6y agoWomen have been sold on the idea from a very young age that they need a fairy tale wedding to live happily ever after: from toys to tv, from books to movies: the kneeling groom to be with the shiny ring and the large, grand wedding with a dozen bridesmaids. There are multiple industries selling this vision. Reducing that to "but many women will still want something expensive "just so that the man will prove that she matters to him by buying her something"" .... this is pure sexism.
- DFHippie 6y agoAnd there are plenty of women who find this custom distasteful. Some women want a wedding which displays opulence and in which they are treated like a princess. Others want one which more implies the equality of the wedding partners in responsibility and capability. Others want a humorous circus or something that emphasizes the roles of their community in their future lives. Many don't want to start their married life, or any stage of life, with a financial setback.
- Ensorceled 6y agoOh, agreed. I'm just saying what the social environment is. The environment boys grow up in is just as toxic, if not more so, for entirely different reasons.
- unFou 6y agoNot sure what you mean by sexism. But there are differences in the sexes with regards to the process of conceiving and rearing a child. And it seems to me that a big part of our social constructs that were developed to deal with those differences can be reduced to "the man doing something expensive and hard to fake". Which isn't really that different from "the man proving she matters to him by buying something".
- Ensorceled 6y agoA dowry is a social construct not a "difference in the sexes"
- pritovido 6y agoI think this is not sad, they are free to demand whatever they want, like you are free to accept that. In fact, it is not a very good idea to accept that. You will be labeled instantly as "provider", not as a "lover". Most women that have "providers" also have "lovers" and usually it is not the same person. That is a lesson that I learned long time ago, when I met a very successful with women man, that actually treated them very badly. He had the mentality that it were women the ones that should prove their value to him. Over the years I met other people with the same mindset, and even started applying it somewhat myself. I am physically attractive and educated, but I also was for some time too much polite with women, putting them on a pedestal for being successful with them. The most attractive thing for women is character strength. Also things like being a world traveler helps a lot. You can be penniless, if you have those two things, attracting all the women you want is no problem.
- mrmonkeyman 6y ago> Most women that have "providers" also have "lovers" and usually it is not the same person. Women should know this works both ways..
- imtringued 6y agoIt would be better if they replaced the ugly rock with something prettier and then used the saved money on something that actually keeps its value like gold.
- alilsumpinditto 6y agoperhaps you should watch the video and read the article. It literally states several times it has nothing to do with the advancement in the manufacturing of the type of diamonds people wear as jewelry, but, rather the type used in industry for cutting.
- suprfnk 6y agoWhile you are correct, there is no need to be snarky. One of the guidelines states that: > Please don't comment on whether someone read an article. "Did you even read the article? It mentions that" can be shortened to "The article mentions that."
- CalRobert 6y agoFor what it's worth, not all partners demand diamonds! We deemed a _very_ modest ring and paying off more student debt as the more reasonable option.
- thdrdt 6y agoI also think this is a US thing. In other countries a ring without diamond is also normal. And I guess most people could not even distinct a diamond from polished glass.
- nottorp 6y agoSpeaking of US things, what's an engagement ring? :) And yes, most wedding rings around here are plain gold. I only know one couple with diamonds on their wedding rings and they're kinda nouveau riche and snobby.
- CalRobert 6y agoWe're American, but living in Ireland, and when my wife announced she was engaged her colleagues demanded to see her ring, oddly. Cultural imperialism I suppose.
- tremon 6y agoEngagement rings are as much a thing in Europe as wedding rings, they just don't automatically include big diamonds.
- _0ffh 6y ago>The team applied pressure equal to 640 African elephants on the tip of a ballet shoe Tripe like this is does not help in making sense of the (now missing) numbers. What's the problem with something concrete like kg/sqcm?
- morsch 6y ago(1.2×10^6 to 4×10^6) kg/cm^2 https://www.wolframalpha.com/input/?i=weight+of+640+African+elephants+%2F+square+cm https://www.wolframalpha.com/input/?i=weight+of+640+African+... Unfortunately Wolfram Alpha does not know the area of the tip of a ballet shoe.
- throwaway_pdp09 6y agoNor do I, nor I imagine many others, which makes this supposedly layman friendly term a wide miss.
- _Microft 6y ago~2cm x 5cm seems reasonable for the tip of a ballet shoe, so I'd say about 10 to 15cm^2. https://en.wikipedia.org/wiki/Pointe_shoe https://en.wikipedia.org/wiki/Pointe_shoe
- dogma1138 6y agoThat part of a pointe shoe is called the platform it’s size and shape varies greatly based on the type and size of the shoe and the box (the part of the shoe where your toes sit in). For most pointe shoes with a rounded platform there is much less than 10cm squared of contact.
- unnouinceput 6y agoYou can safely assume a tip of a ballet shoe has around 2 x 2 cm so 4 square centimeters as area.
- danaur 6y agoThe concrete number while it would be nice to include is a lot less helpful for the average reader than something more illustrative like the elephant number.
- billpg 6y ago"Artificial" diamonds. Unless I've misread something, these are genuine diamonds. IE, carbon crystals. "Artificial" makes people think of moissanite and similar materials.
- init 6y agoIn common parlance "artificial" means man-made. Moissanite can be naturally occurring so it's a diamond-replacement or a "fake" diamond when used in rings and jewelry.
- billpg 6y agoThen "artificial" adds nothing. Just call them diamonds.
- sharpneli 6y agoIt depends. In case of Artificial leather it refers clearly not to lab grown animal skin but to a completely different product that just tries to emulate leather. So the word is used in different contexts. And De Beers is more than willing to use the term artificial diamond. They can claim that they're not lying, but they're also very happy that it's also easy for customers to think its artificial in the fake sense, not in the man-made sense.

- thdrdt 6y agoThe paper: https://onlinelibrary.wiley.com/doi/epdf/10.1002/smll.202004695 https://onlinelibrary.wiley.com/doi/epdf/10.1002/smll.202004... (you need access to see all parameters). Anyway it looks like they created a very tiny diamond. So it looks to me we should not expect man made diamond rings soon.
- markvdb 6y agoSynthetic diamonds for use in jewellery exist and are quickly gaining in popularity [0]. If buying a diamond ring, you might want to get a synthetic one instead of a mined one [1].

- derbOac 6y agoFwiw, my wife wanted a synthetic diamond and we found they were much more difficult to obtain in practice than was acknowledged. Like going to a listing of many many stones but they were all unavailable because they were out of stock or backordered or no one would ever respond. My sense at the time the supply and/or market were inflated to attract investors and maintain attention. I do hope that's changed because we were really interested. But at the time it was a big mirage.
- codeulike 6y agoWe've had human-made diamong rings for years, and their existince highlights the preposterous nature of the whole diamond-jewelry industry Lab-grown diamonds raise profound existential questions for the industry: for one, if chemically identical stones can be grown in a lab, what is the point of mining natural diamonds? https://www.ft.com/content/8b502874-feee-11e8-ac00-57a2a826423e https://www.ft.com/content/8b502874-feee-11e8-ac00-57a2a8264...
- Aeronwen 6y agoDiamonds aren't rare. The preposterous nature of the whole diamond-jewellery industry is that it's based on hiding that fact to create false scarcity.
- Synaesthesia 6y agoSo they’ve made a new form of carbon, which may actually be harder than Diamond.
- ncmncm 6y ago"Lonsdaleite, which is predicted to be 58 percent harder than regular diamonds" We have had lonsdaleite from meteorite sites (and all over the world at 12,900 ya and 66 mya), but apparently not big enough to measure hardness?
- jleahy 6y agoBig enough to measure hardness, and we've been able to make it ourselves since the 60s, but in measurements it's always less hard than diamond. Only in computer simulation is it actually harder. I guess they glossed over that bit as it makes it sounds less exciting.
