Artificial diamonds creation process generating lonsdaleite

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?
I guess they glossed over that bit as it makes it sounds less exciting.
Unless I've misread something, these are genuine diamonds. IE, carbon crystals.
"Artificial" makes people think of moissanite and similar materials.
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.
Because lab-grown animal skin is not on the market (as far as I know), so artificial implies that it's fake. If it were, though, and at least roughly as common as fake leather. I'm sure no-one would try to refer to it as natural. It would still be artificial, and artificial would cease to imply it being fake.
If people choose to refer to fake leather as artificial leather, it's because artificial, real leather was hardly in the realm of the imaginable. Many would refer to it as impossible or at least as an act against God.
> So the word is used in different contexts.
What's being used in different contexts is the word "leather" to refer to both real and fake leather.
"Artificial" is always used to refer to the non-natural, the man-made. I can't think of any case where it's used differently.
made or produced by human beings rather than occurring naturally, especially as a copy of something natural.
"her skin glowed in the artificial light"
Natural: Mined. Synthetic: Lab grown but real. Artificial: Another substance that looks similar.
Random thought, someones going to make bank growing synthetic leather.
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?

Unfortunately Wolfram Alpha does not know the area of the tip of a ballet shoe.
For most pointe shoes with a rounded platform there is much less than 10cm squared of contact.
I can roughly envision a giant pile of elephants exerting force on a tiny patch of ground better than I can interpret PSI or atmospheres.
The point is not to convey an exact amount. It is to say “it’s a shitload”.
For a mammal, maybe. For the rest of Animalia that’s not extreme at all.
And of course if you ever talk about bovines you will have to use the standard spherical cow as a measure.
As for the spherical cow, is that a metric sphere or a US customary sphere?
kg isn't a measure of force. And the world will be a nicer place once we retire the oddball prefixes of centi, deci, deka, and hecto.
Why? Is that just so we have fewer things to remember, or is there a more obvious benefit I'm missing?
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.
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.
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".
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.

And I guess most people could not even distinct a diamond from polished glass.
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.
Anyway it looks like they created a very tiny diamond. So it looks to me we should not expect man made diamond rings soon.
I do hope that's changed because we were really interested. But at the time it was a big mirage.
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?

The preposterous nature of the whole diamond-jewellery industry is that it's based on hiding that fact to create false scarcity.
