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.

UAE-based designer creates modest fashion at a modest price

DUBAI: For many modest fashion designers, it was the difficulty of finding stylish, high-street staples that played a role in why they initially set up shop. For Mosika Zeid, it was during her transition to hijab that she had her very own “a-ha” moment.
“[It] was honestly a fashion disaster,” the designer says of her time when she first started to wear a headscarf. “Being someone who was very fashion-conscious, and who loved to keep up with the latest trends and always look their best, I was shocked that I could not find everyday, on-trend modest fashion that had a reasonable price tag.”
Zeid, 33, is founder and CEO of the UAE-based modest fashion brand Desert Cove. It was as a lawyer that the Australian designer of Palestinian descent made her foray into the world of fashion.
“I was exposed to the fashion industry when I first started working as a lawyer over 12 years ago in Sydney and had some of the largest luxury fashion houses as my clients,” Zeid said. “When I came to the UAE, I consulted for some of the largest retailers. Through this I got an even greater insight into the business of fashion, as well as apparel production, sampling, fabrics and the whole process. And I just loved it.”
In July 2016, Desert Cove was born.
“This was a very soft launch,” Zeid said.
“The idea was just to test the market response to the concept.”
Receiving “an amazing response” encouraged Zeid to continue, and now she’s working on her third collection. Most recently, her team headed to Indonesia to show at Jakarta Modest Fashion Week. “It was an amazing experience to connect with our South East Asian customers and to confirm that our sisters in that region are interested in Desert Cove,” she continued.
Another location that’s exciting to the designer at the moment is the Kingdom. “Saudi women have an impeccable sense of fashion and style. They are world class, so their requirements for fashion are also world class,” says Zeid.
“The fashion scene in Saudi Arabia is undergoing huge changes [and] this means that women are looking for day-to-day fashion inspiration, which meets their amazing fashion sense, while still not compromising on their modesty requirements.”
For Zeid, Desert Cove’s unique selling points are two-fold. “Firstly, we are one of the few brands dedicated to providing hijabis modest versions of the hottest mainstream fashion trends. Plus, we have a $50 price promise on our main collection items, and $100 on our exclusive retailer collections.”
Looking ahead, Zeid is now focusing on Desert Cove’s upcoming spring-summer 2019 collection, as well as distribution deals and Dubai Modest Fashion Week at the end of 2018. “We have just launched in House of Fraser in Yas Mall in Abu Dhabi and will be having a launch event in store in early October, which we are very excited about,” she revealed.
Needless to say, Zeid doesn’t have any regrets about setting up. “I am so happy that I did launch Desert Cove, as I really do feel that I am contributing to solving a problem that women are facing, helping them to feel better about themselves and lead their most active and productive lives that they can.”
