It takes a lot to make a diamond burn — but it can be done. Watch these people prank a Nobel Prize winner, while demonstrating that diamonds are made of carbon and can burn like carbon.
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 harbor diamonds has vaulted the plant out of obscurity.
Evening Shade (!) resident Susie Clark was visiting Crater of Diamonds State Park in Murfreesboro, Arkansas when something caught her eye: a 3.69 carat diamond. Clark discovered the diamond, which is the size of a “pinto bean,” while walking in the park’s search field.
Many people know that diamond is actually pretty common when it comes to gemstones (you can find millions of them in your typical candle flame), but who among us can actually name any that are rarer? Here, we present to you a collection of ten of the rarest gemstones on Earth.
Geologists now suspect that an entire ocean's worth of water exists deep inside the Earth's crust. The discovery of a diamond-like grain made of ringwoodite — a water-rich mineral previously seen only in meteorites — suggests that vast volumes of water are trapped 250–400 miles beneath the surface of the planet.
For the first time ever, geologists working in Antarctica have found a type of rock that's known to bear diamonds — a discovery that could expose the polar continent to opportunistic prospectors.
If diamonds are just lumps of precisely-structured carbon, why don't they burn? Actually, they do. And proving that they do is one of the things that cost a famous scientist his life.
Back in the 1970s, the Soviet government discovered a rather remarkable deposit of precious gems in a 100 kilometer (62 mile) crater located in eastern Siberia. Called the Popigai crypto-explosion structure, it contains "impact diamonds" — massive mineral deposits that formed when an asteroid hit the area 35-million…
Everyone knows that humans can make artificial diamonds. But did you know that we can make sapphires, emeralds, and rubies as well? Did you know that this involves weird occult-like instruments, like little rooms lined in gold? Starting with crystal seeds and watering regularly with hydrochloric acid, we can grow a…
The Hope Diamond intrigues people with its beautiful blue color, its mysterious curse, and its sheer size. But did you know it glows "like a coal on a barbecue grill" for several minutes after it has been exposed to UV light? Learn the scientific secrets of the glowing blue diamond.
Black diamonds, also known as carbonados, are dark, porous, and found only in Brazil and Central Africa. And they don't come from volcanoes — they come from outer space.
A few months back, astronomers discovered a diamond planet formed from the remnants of an exploded star. It looked like a cosmic oddity, but giant diamond-encrusted planets might be way more common than we ever suspected.
An international research team has found an exoplanet made entirely of diamonds. Although this may seem glamorous, researchers think it is only the desolate remains of a star, robbed of its mass by its companion.
It's no mystery that diamonds are, in fact, one of the world's most completely-not-rare "rare" gems, but it seriously feels like they're becoming more and more common every day. Case in point: scientists have discovered that for the price of a candle, you too can be the proud owner of millions upon millions of…
Some of you are undoubtedly considering a sexy, lucrative career in the rarified world of cat burglary. For all you would-be dapper scoundrels, here's a recent medical paper that'll be of interest. It's about the dangers of swallowing your prizes.
Researchers have figured out a way to make diamond aerogel. The aerogel is only 40 times as dense as air. Someday, it may coat the windows, the TV, and the inside of a person's body.
Computers are always getting smaller and more powerful, but shrinking things down isn't just a matter of developing better electronics. A great number of practical things need to be considered when cramming technology into a small space. For example, the simple need to keep things cool. More powerful stuff pushed…
Find out which parts of the world to visit if you want to walk away with diamonds on the soles of your shoes.
Dinosaurs may not have been Earth's only creatures to face extinction from above. A team of researchers has found evidence that suggests a comet once hit North America, taking the continent's mammals down with it.
Usually when a large meteor hits the Earth, it's a cataclysmic event that heralds the extinction of various species. But they also mean lots of diamonds. The latest cache of meteor-made diamonds was just discovered in California.
