Massive diamond cache detected beneath Earth’s surface

  • “This shows that diamond is not perhaps this exotic mineral..."
  • These naturally occurring precious minerals are located far deeper than any drilling expedition has ever reached

WASHINGTON: 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 analyze 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 center 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 percent 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.

Destiny’s designers: Kelly Rowland, Beyoncé don Arab gowns at charity event

DUBAI: Kelly Rowland and Beyoncé both chose Middle East-based designers for their trip down the red carpet at a charity event last week.

The superstars attended the City of Hope Gala in Santa Monica, California, wearing floor-length gowns by designers from Kuwait and Lebanon.

For her part, Rowland chose a glittering, rose gold gown by Kuwaiti designer Yousef Al-Jasmi, with a high collar and slit at the back. She accented the figure-hugging dress with a pair of dazzling earrings and slicked-back hair.

Meanwhile, Beyoncé chose a black velvet jacket by Lebanese label Elie Saab. The belted piece featured embellishments on the shoulder and a plunging neckline and is from the label’s Autumn/Winter 2016 collection.

Beyoncé paid homage to a high-profile music executive being honored at a charity event to raise money for cancer research, The Associated Press reported.

The singer’s vocals soared as she performed three ballads including her 2009 smash hit “Halo” and “Ava Maria” after saluting the character of Warner/Chappell Music Publishing CEO Jon Platt at the City of Hope gala near Los Angeles on Thursday night. She took the stage following her husband, Jay Z, who presented Platt with the Spirit of Life award during a charity event that raised more than $6 million.

“Most people lead with their ego, but you lead with your heart,” Beyoncé said Platt, who will soon be leaving his position at Warner/Chappell to take on the top role at Sony/ATV, the top publishing company in the music business.

“You have touched so many lives, mine included,” she added.

Jay Z called Platt the “Obama of the music industry.” The music executive is known for signing publishing deals with Jay Z, Usher, Kanye West and Snoop Dogg. His roster of songwriters at Warner/Chappell includes Lil Wayne, Bruno Mars and Timbaland.

Both Beyoncé and Jay Z appeared at the black-tie charity event after the couple wrapped up their On The Run II tour about a week ago.

“I can’t think of anyone more deserving of this award than my brother, Jon Platt,” Jay Z told more than 1,000 attendees. “He’s known as ‘Big Jon’ and he has a beautiful soul.”

City of Hope is a treatment center for cancer, diabetes and other life-threatening diseases as the Music, Film and Entertainment Industry Group has raised more than $118 million in 45 years. The award is the group’s highest honor recognizing those that have helped further music, film and entertainment.

Previous Spirit of Life award recipients include Quincy Jones, Clive Davis, Irving Azoff and Mo Ostin.

Music mogul Diddy, singer Usher, former NBA player Chauncey Billups and some of Platt’s family members took part in a video dedicated to the music executive. Platt’s oldest son, Jonathan Platt, was diagnosed with diabetes.
