There's a load of bling buried in the Earth.
More than a quadrillion tons of diamonds to be exact -- or one thousand times more than one trillion -- US researchers at the Massachusetts Institute of Technology reported this week.

But don't expect a diamond rush. These naturally occurring precious minerals are located far deeper than any drilling expedition has ever reached, about 90 to 150 miles (145 to 240 kilometers) below the surface of our planet.

"We can't get at them, but still, there is much more diamond there than we have ever thought before," said Ulrich Faul, a research scientist in MIT's Department of Earth, Atmospheric, and Planetary Sciences.

"This shows that diamond is not perhaps this exotic mineral, but on the scale of things, it's relatively common."
Using seismic technology to analyse how sound waves pass through the Earth, scientists detected the treasure trove in rocks called cratonic roots, which are shaped like inverted mountains that stretch through the Earth's crust and into the mantle.
These are "the oldest and most immovable sections of rock that lie beneath the centre of most continental tectonic plates," explained MIT in a statement.
The project to uncover deep Earth diamonds began because scientists were puzzled by observations that sound waves would speed up significantly when passing through the roots of ancient cratons.
So they assembled virtual rocks, made from various combinations of minerals, to calculate how fast sound waves would travel through them.
"Diamond in many ways is special," Faul said.
"One of its special properties is, the sound velocity in diamond is more than twice as fast as in the dominant mineral in upper mantle rocks, olivine."
They found that the only type of rock that matched the speeds they were detecting in craton would contain one to two per cent diamond.
Scientists now believe the Earth's ancient underground rocks contain at least 1,000 times more diamond than previously expected.
Still, very few of these gems are expected to make their way to the jewelry store.
Diamonds are made from carbon, and are formed under high-pressure and extreme temperatures deep in the Earth.
They emerge near the surface only through volcanic eruptions that occur rarely -- on the order of every few tens of millions of years.

Diamond in fact is carbon the same as coal.

When there are so much of diamond by trillions of tons, they should become cheaper than coal!

In future I will BBQ chicken wings & mutton in diamond flame as fuel replacing charcoal.

Diamonds from hell: A quadrillion tonnes of precious gems found inside the Earth

Scientists have discovered a quadrillion tonnes of diamonds, and the good news is they're right here on Earth.
Or perhaps more accurately, in the Earth - and that's the catch. No one can reach them.
Researchers in US came across the huge stash whilst investigating an anomaly in seismic data. Sound waves that travelled through the Earth following quakes and tsunamis speed up when passing through parts of the Earth just beneath the crust.
"The velocities that are measured are faster than what we think we can reproduce with reasonable assumptions about what is there," said Ulrich Faul, MIT research scientist.
"Then we have to say, 'There is a problem.' That's how this project started."
Crunching the numbers led them to a sparkling discovery - between 1 and 2 percent of the rock beneath the Earth's tectonic plates is pure diamond.

• The world's largest diamond sells for $73m
• Massive 706-carat diamond found in Sierra Leone

"This shows that diamond is not perhaps this exotic mineral, but on the [geological] scale of things, it's relatively common," said Mr Faul.
Much, much more - 1,000,000,000,000,000 tonnes, if you write it out as numerals. That's equivalent to the weight of 3 trillion Boeing 747s.
Diamonds' value comes about partly because of their scarcity, but don't expect engagement rings to get any cheaper right away - the closest are about 140km away.
"We can't get at them, but still, there is much more diamond there than we have ever thought before."
The deepest hole in the world ever drilled went down only 12.2km. It had to be stopped due to temperatures upwards of 180degC.

The researchers say the only way we'll get to the diamonds from hell would be if they're spewed up by a volcano.
The research was published in journal Geochemistry, Geophysics, Geosystems.

Geologists think there could be a quadrillion tons of diamonds inside our planet

But we’ll never get them out of the ground.
By Neel V. Patel Yesterday at 6:00am

The diamonds in the Earth's interior definitely don't look like this.

Despite their incredible reputation for being exquisitely rare and valuable, diamonds are more common than you might think. Other planets, like Uranus, are probably chock full of them. They’re floating around on some space rocks even right now. As it turns out, us Earthlings might be sitting on top of a motherlode of diamonds — one quadrillion tons, actually.
Over 100 miles under the Earth’s surface is a section of geology known as cratonic roots. They sit beneath what geologists call a craton, the oldest, most stable section of rock within a continent. Some reach deep into the interior of the Earth—capable of stretching down as much as 200 miles deep, through the outer crust and into the planet’s mantle —hence the “roots” label.
“Cratons are intimately associated with the some of the most significant events in Earth history, such as the initiation of plate tectonics and the formation of the continents,” says Joshua Garber, a postdoc at Penn State University and the lead author of the new study. “They have been stable since the Archean Eon, at least 2.5 billion years ago, so they've had plenty of time for lots of happen to them…they've been chemically stewing in that mantle for a long time.” The findings fold into a larger effort to understand the history and processes in the superficial and deep mantle regions of the earth.
In a new paper published in Geochemistry, Geophysics, Geosystems this week, an international team of researchers estimates that about 1 to 2 percent of the Earth’s cratonic roots are made of diamond. That might seem like a small amount, but that tiny fraction is makes up enough of these massive geological formations to account for a quadrillion tons of diamonds. That’s the number 1 followed by 15 zeros!
The research team wasn’t looking for shiny gems when it made this discovery. For years now, scientists have collected an enormous amount of data pertaining to the seismic activity of the Earth. That data can be used to create a sort of 3D dimensional map that outlines what the Earth’s insides look like.
But not all seismic data adds up equally. Much of it is made using sound wave measurements emanating from the Earth after they are triggered by earthquakes, explosions, and other events. These sound waves (also called shear velocities or frictional velocities) travel at different speeds depending on the type and temperature of the material they’re moving through, and so they move faster through the roots of ancient cratons since they are colder and less dense than the surrounding mantle rock. But the shear velocities are speeding through craton roots at higher than expected velocities.
“Such high shear velocities would be expected if temperatures are much colder than average at that depth,” says Barbara Romanowicz, a coauthor of the new study and a seismology researcher at the University of California, Berkeley. “But you would need unrealistically low temperatures compared to what we know about those regions of the mantle, for standard rock compositions.”
The team wanted to know what would account for the unusually quick velocity readings. They began their investigation by using the data they had to create a 3D model of the seismic waves zipping through the craton roots, followed by laboratory tests of sound waves traveling through various earthly mineral combinations, heated to temperature profiles one would expect to find in the craton roots.
Cratons are predominately made up of peridotite, but can’t exhibit high shear velocities. There were only two other minerals that exist in earth’s mantle that could have explained the speeds: eclogite (subducted oceanic crust descending into the mantle zone), and diamond.
You would need an unrealistic amount of eclogite to facilitate the observed shear velocities. Meanwhile, “diamond has extremely fast shear velocities, so you would need only a little bit of it, especially if combined with eclogite, to match the observations,” says Romanowicz.
The only rock structures in the lab tests that accounted for the speeds observed in nature possessed just a sprinkling of diamonds—1 to 2 percent. That was enough to reconcile the discrepancies in the sound wave data, without affecting the overall measured densities of the craton roots.
While the findings are a bit unexpected, they make tons of sense (though maybe not quadrillion tons worth of sense). “Diamond is a really attractive answer because it is so much stiffer than most other minerals,” says Garber. “One outcome of this study is that, if the answer is not diamond, there has be quite a bit more of some other stiff constituent besides diamond that we have even less evidence for.”
In addition, Romanowicz says it’s possible the craton diamonds could come from carbon-containing fluids rising up from subducted slabs (diamonds are essentially stable forms of carbon, created by extremely high temperatures and pressures).
But don’t get too excited now: you will never, ever see these pretty rocks in the flesh. Again, they’re located over 100 miles underground — “that is about 10 times deeper than the deepest hole ever drilled into a continent,” says Romanowicz. “Drill bits get used up very quickly and soften as you attain high temperatures in excess of several hundred degrees Celsius, and even cooling by water injection is not enough to compensate. I frankly don't think this is going to happen any time soon."
“On the other hand,” she continues, “diamonds do come up to the surface carried by ancient volcanism. And there may be more out there than has already been found,” given what the findings suggest, “so there is hope there.” We might just have to be patient, but when it comes to time on a geological scale, that sort of patience might have to endure beyond our species’ own existence, let alone our own current lifetimes.
Moreover, would you really want to? If there a quadrillion tons of diamonds being passed around on the surface of the Earth, these gems suddenly wouldn’t seem as precious as they do now. Diamonds would probably become as valuable as a copper penny. (Although Lincoln’s face etched on the face of a diamond would definitely be a brilliant change.)

So those who INVESTED in Diamond can jump MRT ASAP!

@ginfreely did you?

Ha? Yes? Go Blame Malaysia & Dr. M for that! Don't blame your own silly GREED!

Huh? You expect Malaysia or PAP to cover your losses? I see... You Bumiputra or RC Bitch?

Quadrillion tons of diamond is buried 145 to 240 kilometers below earth's surface

Hmm....

Time to use diamonds to pave road surface instead of granite. Mixed in concrete in place of quartz sand to build houses etc.

Diamonds will be cheaper than shattered glass.

Reminds me of the game motherload.

Diamonds are just like clam shells, value lies in the eye of the beholder. In this case, usually the blind.

Anything can be valuable if u restrict the supply.

 

[Hypocrite-The]

Diamonds have been a bad investment for the past decades. Artificial diamonds with the same chemical composition are being made on an industrial scale. The only thing that holds value is gold.

Some would now say bitcoins too

At least diamonds are a physical entity. Can touch can hold.. bitcoins leh?

bit coin = BIT CON

Crypto currencies are Scams.

 

[frenchbriefs]

bit coin = BIT CON

Crypto currencies are Scams.

Anything in the world can be a scam including ur hdb,its faith,trust and demand what gives an object its value.

Besides bitcoin is a currency,its purpose is to transfer value from one person to another and facilitate trade.....it never claim to be anything else.......if the world decides to adopt bitvoin as its currency,its value will skyrocket overnight.....of course bitcoin as a currency has its flaw namely its limited amount like hdb flats which means its susceptible to inflation and easily cornered.

Gold, Bitcoin or 99 year hdb... Which is better store of value over 30-40 year period?

Gold of course....gold has been around for thousands of years and always in demand.....no currency or hdb has lasted more than 100 years yet.
