Rare Blue Diamonds Lurk Deep In Earth's Core (washingtonpost.com)
Scientist believe they now know how extremely rare blue diamonds are formed. After studying 46 of the gems, they found that blue diamonds are formed as deep as the transition zone between the planet's upper and lower mantle (Warning: source may be paywalled; alternative source) -- far greater depths than other diamonds, some deeper than 410 miles. The Washington Post reports: Just 1 out of 200,000 diamonds are blue. Like all diamonds, they are made when carbon comes under intense pressure and extreme heat deep inside the Earth. As they form, they can trap tiny bits of rock inside -- like fossils in amber. "Diamond is an extraordinary container, a time capsule," said Steven Shirey, a geochemist at the Carnegie Institution for Science in Washington. Shirey and his colleagues used lasers to examine the diamonds' imperfections -- slivers of embedded rock -- at the Gemological Institute of America. The researchers suggest that boron in the ocean floor was pushed down when plates that make up the Earth's crust collided. The element allows the stone to absorb some red light, so the diamond looks blue. The findings were published in the journal Nature.

their sidekicks.. other stuff... some still calling this 'weather'?
already boarding; the self-chosen crown royals, some gargoyles, many virgins, monkeys, slaves...not really much room left.. the real sidescam is to still be here, after.. whatever.. the 1 person submersible bunkers are no great invention either? synthetic oxygen? phewww... just kidding of course..
Specifically they lurk in my wife's engagement ring. Go ahead Slashdot trolls... Bring on the hate for being married on Slashdot.
But in all seriousness, that's the beauty of lab created gemstones. You want a blue diamond? Not really any different than creating a clear one. You can even pick from different shades of blue.
Yes it's an anecdote! Were you expecting original research in a Slashdot comment?
... is exactly why humans values these stones so highly. Sure, they're hard, but thats a pretty niche use. Apparently they look pretty. To me they just look like bits of glass which also doesn't tarnish. I honestly don't get why our species craves this stone so much.
It's got electrolytes.
The deepest mine in the world is about 4km underground...
If all you have to do is add a little of element X to get color Y in a diamond then it seems like it shouldn't be long until they start growing them in a lab like this. The bizarre thing is that people actually want these shiny chunks of carbon.
Anons need not reply. Questions end with a question mark.
Or roughly 2.5 Miles. Yes the US should change to the Metric System, but why mix measurement systems in a comment post. It only adds to confusion.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
TFS summary says they're formed in the mantle, not the core.
The deepest mine in the world is about 4km underground...
The main obstacles to going deeper are getting air in and getting heat out. The solution is to get humans out and robots in. Robots don't need oxygen, and they can tolerate much higher temperatures. They can also work in much narrower shafts, and can even work submerged in pressurized liquids that can reduce cave-ins. There are also huge savings from avoiding all the safety measures, shift changes, and even gem theft.
That's sideways. If mining companies went straight down, they would reach China and owe the Chinese government mining royalties.
she sucked my blue balls dry.

No actually, we won't...
But in all seriousness, that's the beauty of lab created gemstones.
Much more interesting : which lab did you go to ?
For the extra geekiness factor : do you know any lab that they would allow big geeks to do a couple of the step ?
(As in "Honey, I personally *made* your diamong ! (Well I least until the labcoats threw me out before I break the expensive machines)" )

This is the attitude that keeps the US from switching in the first place.
Laws are rules for the court, but merely a bottom bar to hit for life. Think beyond laws in your actions always.
Why buy her a diamond? I had that printed on a tshirt once. I was selling rubies and was the only one in the show not selling diamonds. It was hilarious. I gave away 100 shirts and people were wearing them everywhere. Obviously, I was hated by the other dealers.
1. They are not that rare. Thanks DeBeers for creating and maintaining an artificial scarcity for close to 100 years now. 2. They became THE engagement ring thing not so long ago. Again, DeBeers is responsible for the underlying marketing ploy. 3. They are a lousy investment. Ordinary diamonds, like the ones that normal people can afford, instantly lose 50% of their value as the leave the jewelry shop.
Real Lucky Charms only had pink hearts, yellow moons, orange stars, and green clovers.
None of this blue diamonds bullshit. Or horse shoes. Or shooting stars. Or blue moons. Or rainbows. Or red balloons. Or UNICORNS!
No wonder kids are fat these days.

The only good purpose for diamonds is in the tip of a drilling or cutting tool. The rest is only douchebagery and foolishness.
If you like to have things built with a mix of measurement systems, come live in Canada!

...the Earth's core could use some freedom.
Alright, but don't send Bender otherwise that last part won't be true.

"if shes not"?
they're going to continue to lurk. Ain't know way we can polish them and admire their luster.
Sorry, no.
The main obstacle is literary.
"Journey To The DeBeers Diamond Mine At The Center Of The Earth" just doesn't have the same ring and doesn't roll off the tongue as smoothly.

Progressivism (aka US 'Liberalism'): Ideas so good they need a police/surveillance-state to enforce.
Look for them to hike the price and hoard them like they do the entire world's supply of diamonds. A pressurized hunk of carbon...made "expensive" and they have a nice monopoly.
You're correct, but there's more to it.

This is where I grew up. See how the roads are spaced pretty regularly? Those aren't kilometers.
There's a huge amount of our country that's based on imperial measurements, and those for whom metric makes more sense - such as in science - already use metric. There's really no reason to change.
Do you have ESP?
You can find them in every bowl of frosted Lucky Charms (they're magically delicious!)

Huh. So that movie actually got something right.
The reason to change is that it's really annoying to mix systems, as the grandparent said. Wouldn't it be nice for consumers to actually be able to tell if something they're buying by the liter is cheaper than something they're buying by the gallon? Wouldn't it be easier if all those 5K races Americans run related to distances they drive? Wouldn't it be nice if the common American could understand science news without having to convert back and forth in their head? How about cooking a meal where half your measurements are in imperial and half in metric? Tired of weighing medicines in milligrams and other things in ounces?
The US has already adopted the metric system, but only as another set of random incoherent measurements along with our teaspoons and cups and miles. All we have to do is simplify by removing the unnecessary units.
And who cares if roads are 1 mile apart or 1.6 km apart? Most of us aren't OCD about road spacing and few places are laid out like that anyway.
