Hi, I’m Sage, and this is Crash Course Geology.Diamonds. They’re bright, flawless, and a girl’s best friend.These aren’t real by the way.
we're about to take on right pressure creates diamonds right pressure createsdiamonds it's not possible to have these beautiful diamonds without pressure and therefore for all of us there's different wayswill be pressurized in our inner journey but learning that it's an inner journey is extremely open important and what I
Oh, I'm sorry. Why would we propose with a diamond, question mark?Diamonds last forever. Diamonds last forever.And who told us that?
Not the sort of thing you normally admit to at a public event, but I notice about eight of you perked up there.Diamonds. Diamonds. Diamonds, diamonds, diamonds.
right working in secrecy is it can be very very alienating this imagine havingdiamonds so probably the the shape of the patch is uh represents the shape of the airplane and this bottom part where
They’re stable, hot, and pressurized enough to form carbon into that super dense crystal structure that diamonds are known for.Most diamonds form in Earth’s upper mantle— the part right below the outer crust.But some diamonds, like the Hope Diamond, form even deeper down, in the transition zone and lower mantle— more than 600 kilometers below the surface.
All right, so we know the diamonds are made of carbon, and that heat and pressure transform diamonds-- diamonds-- and we know that heat and pressure transform carboninto diamonds. Could a diamond then be-- could you reverse that?Could you actually make a diamond in a laboratory setting?
Blue was always tough for a geography clue.Blue diamonds was this rare stone that I found.And I was going to clue it as, "This precious South African export--" something like that.
greed-driven. And we look at things like cocaine finance guerrillas in Colombia, or opium finance insurgents in Afghanistan, orblood diamonds in West Africa.We all know the term blood diamonds now.
They're also a solid state sensor, which, you know, can be very practical for some applications and can be made into like a more robust kind of sensor.- These are the diamonds mentioned in the New York Post article.So how do they work?
And we used to have all these battles.And like diamonds, the raindrops would spray out of their feathers.
Sure, coal is also made of carbon.But the way diamonds actually form is way cooler than squishing a sooty rock.Let’s dig a little deeper… For hundreds of years, humans didn’t know where diamonds came from.
And after a hundred-odd years, we finally figured out how those special stones got there.It turns out diamonds form in cratons, the deep-down roots of continents.They’re stable, hot, and pressurized enough to form carbon into that super dense crystal structure that diamonds are known for.
Most diamonds form in Earth’s upper mantle— the part right below the outer crust.But some diamonds, like the Hope Diamond, form even deeper down, in the transition zone and lower mantle— more than 600 kilometers below the surface.Maybe that’s why the Hope Diamond is allegedly cursed: it’s seen things no one was ever meant to see.
And the violent flow rips up chunks of deep rock that— if you're lucky— are studded with diamonds.As for super-deep diamonds like the Hope, they have to rise a bit higher in the mantle first, possibly by hitching a ride on extra-hot rock that flows from the lower mantle to the upper.Then, kimberlite eruptions can blast them to the surface.
Most kimberlite eruptions happened between 250 and 50 million years ago.And their diamonds started forming long before the blasts, up to 3 billion years ago.Talk about classic rock.
That one was so bad it’s good.Which helps us see diamonds for what they really are: time capsules of the past.They have a lot to teach us about the super-deep earth, and its super-long geologic history.
The last kimberlite eruption was 13 million years ago, and we don’t know if another will ever happen again.So while diamonds continue to grow deep underground, we're left to mine the ones that ancient eruptions have already lofted into Earth's crust.That may have given you the impression that diamonds are super rare; after all, we humans have prized them for centuries, and there’s only so many that are accessible to us.
Who would later die of gangrene.Finding the kimberlite diamonds in South Africa had huge effects.For the next almost-century, the African continent produced 98 percent of all the diamonds in the world.
For the next almost-century, the African continent produced 98 percent of all the diamonds in the world.And with so many diamonds flooding the market, they weren’t just for royalty anymore.That’s when British finance bro Cecil Rhodes saw an opportunity.
Modern processes use tiny fragments of natural diamonds to seed new, lab-grown ones, and work way more efficiently than the old techniques.Lab-grown diamonds are real diamonds— they just have a slightly different origin story.Today, lab-grown diamonds are more popular than ever.
In those places, small-scale mining operations often use forced and child labor and sell diamonds to fund violent conflicts.We call those blood diamonds.Even though international organizations have tried to crack down on them, they’re still out there in the diamond market.
I done "All of Me" when I was in the boy band, "All of Me" by John Legend.I've done "Diamonds" by Rihanna.So just another cover.
And what he draws is he free-hands three interlocking diamonds.And those three diamonds will become the center of the Mona Lisa knot.And he starts this preliminary drawing 10 years before he ever starts the "Mona Lisa" painting.
One of them that I'd like to talk about is authenticity and the story of laboratory-grown diamonds, which is really awesome.The first non-natural diamonds were made in General Electric's laboratory in December of 1954.And in the 1940s, General Electric's laboratory in Schenectady, New York was the center for synthetic diamond research, that although there were
And based on these experiments, as well as a number of others that were conducted over the next couple of years, Lavoisierconcluded that charcoal and diamonds were simply forms of the same material.And when he publishes an updated list of chemical elements in 1789, he refers to this substance as carbon.
It's actually not unlike if you think about contemporary rock candy and how rock candy is made, it's a sort of similar thing that Haney is proposing.But obtaining the diamonds that Haney sends to the British Museum-- so in theory, this sounds very straightforward.But the actual practice of how do you actually make this?
And so I also want to point out that Haney is not the only person who is working on this question of how to makelaboratory-grown diamonds. The French chemist Henri Moissan is working on this question.American Charles Parsons--
So over the next couple of decades here in the 20th and 21st century, it's not just GE and industrial diamond-making, new companies and new technologiesfor making the diamonds are developing.
Give me the key.Give me the diamonds, or I'll torture you.And Bond would say something like, I'll never tell you.
So that's the real sweet spot.Seven of diamonds. Seven of diamonds, OK-- let's try this.
So that's the real sweet spot.Four of diamonds. Four of diamonds-- OK.
So that's the real sweet spot.Seven of diamonds. Seven of diamonds.
So that's the real sweet spot.The seven of diamonds-- I will attempt to cut the cards with one hand, get one card to fly through the air about 10 and a half times.
So that's the real sweet spot.For the-- seven of diamonds is your card?
We're going to need-- here, will you name a card?- Eight of diamonds.- OK, eight of diamonds.
- 13. - 13.We have eight of diamonds, 13.And you were holding the card.
- You don't want to change your mind.Eight of diamonds. Same with the number.That was your choice.
De Beers. De Beers, yes.De Beers said diamonds are forever.So if you love her or you love your loved one, you better get a diamond.
Because he understands that we each have the capacity and the potential to achieve greatness.or rough diamonds. We can actually produce beautiful rings,
- The three of diamonds, OK, excellent choice.
Five of diamonds. The?
Five of diamonds. The five of diamonds.
This is five of diamonds?
Jack of diamonds. OK.
We did it with diamonds.
The fact that Zimbabwean diamonds were not considered conflict diamonds is a huge gaping hole in that process.
"Forget oil and diamonds.
