While traditional diamonds are formed over billions of years deep in the Earth where extreme pressures and temperatures provide just the right conditions to crystalize carbon, scientists are working on more expedient ways of forging the precious stones. An international team of researchers has succeeded in whittling this process down to mere minutes, demonstrating a new technique where they not only form quickly, but do so at room temperature.
The team applied pressure equal to 640 African elephants on the tip of a ballet shoe, doing so in a way that caused an unexpected reaction among the the carbon atoms in the device.
The team hopes the technique can enable them to produce meaningful quantities of these artificial diamonds, particularly Lonsdaleite, which is predicted to be 58 percent harder than regular diamonds.

Rare?

But fun to play with expensive machinery.
Let me know when you can turn lead into gold without a nuclear reactor
You can't get medium or well done at room temperature.
Okay, okay. HOW did they get 640 elephants to stand on the tip of a ballet shoe?
I don’t think “african elephants per toe” will ever be a standard unit of pressure.
Asian elephants won’t work. Accept no substitutes!
Gumball machine diamonds coming soon.
A girl’s best friend...
DeBeers will be pissed.

Meh, nobody buys diamonds as gifts anymore, they all buy overpriced cars, I saw it on TV
The reason they push that “A diamond is forever” meme is that they don’t want you to try to sell your diamonds. You’ll find out the resale is nowhere near what they cost originally.
“HOW did they get 640 elephants to stand on the tip of a ballet shoe?”
They say it is “Turtles all the way down” supporting the earth.
A few elephants on top of each other, nothing new.
Prove it? Who counted them??????
I don’t think “african elephants per toe” will ever be a standard unit of pressure.
Some kind of metric standard?
