Beyond the Hype of Lab-Grown Diamonds

Billions of years ago when the world was still young, treasure began forming deep underground. As the edges of Earth’s tectonic plates plunged down into the upper mantle, bits of carbon, some likely hailing from long-dead life forms were melted and compressed into rigid lattices. Over millions of years, those lattices grew into the most durable, dazzling gems the planet had ever cooked up. And every so often, for reasons scientists still don’t fully understand, an eruption would send a stash of these stones rocketing to the surface inside a bubbly magma known as kimberlite.

Here’s How Scientists Bent Diamonds

A team of physicists has figured out how to bend diamonds, according to a new paper. Okay, we’re talking about nano-scale diamond needles here. But it’s an impressive feat, because while diamonds are known for their hardness, these rocks will break if they are bent even a tiny bit. Read More >>

Diamonds Found Packed Inside Rare Meteorite Are Evidence of a Destroyed Planet

Back in 2008, an 80-tonne meteor exploded over the Nubian Desert of Sudan, showering the region with hundreds of tiny rocks. New research suggests the diamonds packed inside these meteorites could have only formed within a planetary body the size of Mercury or Mars—a planet that no longer exists. Read More >>

Ice Crystals in Diamonds Reveal Pockets of Water Deep in Earth’s Mantle

Diamonds, the super-strong and brilliant crystals of carbon atoms produced under the Earth’s crushing pressures, are typically valued for their beauty and durability. But scientists also value them for another reason: They contain all kinds of hidden messages about the Earth’s mantle. You just need the right tools to read them. Read More >>

Massive Diamond Discovered in Lesotho Is World’s Fifth Largest

Workers at Lesotho’s Letšeng mine have discovered an absolute whopper of a diamond, rated at 910-carats. Roughly the size of two golf balls, the precious gem has an estimated value of $40 million (£29 million). Read More >>

Miner Finds Enormous 706-Carat Diamond, Promptly Hands it Over to the Government

A pastor and independent miner in Sierra Leone has unearthed an uncut 706-carat diamond estimated to be worth tens of millions of dollars. The pastor turned the diamond over to the government in hopes that the proceeds from its sale will help the impoverished nation. But given the history of this former “blood-diamond” nation, what happens from here is anyone’s guess. Read More >>

Forgetting a £80,000 Pair of Diamond-Saturated Headphones on a Plane Would Be Tragic

Thanks to Onkyo, throwing on a pair of fancy rose gold Beats headphones is no longer a status symbol. Compared to Onkyo’s new Diamond Headphones which will be available — to a select few — for somewhere around £80,000, those rose gold ear goggles you were so proud of might as well be just another boring pair of white iPhone earbuds.

The World’s Largest Blue Diamond is Up for Sale (If You Have £31 Million)

Fancy treating yourself? The world’s largest ever blue diamond is going up for auction on May 18th at Christie’s in Geneva. But you better have a healthy bank balance: It’s expected to sell for somewhere in the region of $45 million (£31.3m) Read More >>

An Obscure African Plant Grows Only Over Rock That Could Hide Diamonds

Diamonds you’re familiar with. Pandanus candelabrum, not so much. And until recently, botanists didn’t pay much attention to this rare, palm-like plant from West Africa either. But the discovery that P. candelabrum grows only over rock that may harbour diamonds has vaulted the plant out of obscurity. Read More >>

Scientists Use World’s Largest Laser to Recreate Jupiter’s Core

It is not pleasant inside the core of Jupiter—or any other planet for that matter. However, gaining a better understanding of what's going on in there is key for understanding how these planets form. That's why a team of scientists at Lawrence Livermore National Laboratory recently used diamonds and lasers to recreate those very conditions. Read More >>

The Nearly Mile-Wide Diamond Mine That Helped Build the Soviet Union

Building empires takes money. And building industrial empires takes diamonds, not just for cash, but for the machines and tools that need them to operate. In a remote corner of Siberia, the Mir diamond mine was responsible for funnelling diamonds into building the USSR—and it left behind a pit that stretches almost a mile across the surface of the Earth.

Researchers Develop a Way to X-Ray Rocks to Find Hidden Diamonds

It's no surprise that the diamond industry is willing to spend whatever it takes to make the process of mining precious gems even more profitable. And while it already relies on X-ray technology for spotting diamonds on the surface of mined ore, researchers at the Fraunhofer Institute's Development Center for X-ray Technology EZRT have developed a way to now spot them buried inside rocks.

Researchers Found a New, Easy Way to Turn Graphite Into Diamond

Since graphite—the dark material used in regular old pencils—and diamonds are both made from carbon, it's technically feasible to turn the former into the latter. You just need to apply a little pressure—about 150,000 times what the atmosphere on Earth's surface is like. But researchers at Stanford University claim to have found a shortcut. Read More >>
