High pressure experiments suggest large amounts of diamonds are formed from methane on the ice giant planets Uranus and Neptune, while some planets in other planetary systems may be almost pure diamond. Diamonds are also found in stars and may have been the first mineral ever to have formed.
They are - Uranus and Neptune. These two worlds, while iconic for their blue-hazed appearance, are more than just eye-soothing colours. These two planets have conditions that could harden carbon atoms to such high extremes that they form diamonds.
In addition to Saturn and Jupiter, Uranus and Neptune have also been famed for their diamond studded skies. In fact, it was in 1981 that Marvin Ross wrote a paper that proposed that diamonds might be found on these ice giants.
Scientists say a layer of diamonds and rust exists at the boundary between mantle and core.
There is a large diamond on Venus. This diamond helped to prove that Murphy's Law works on other planets besides Earth. The Soviets used the diamond as a front glass to protect the lens of the camera on their spacecraft. Venera 13 and Venera 14 sent back colour photographs of the surface of Venus.
Tidally locked hot Jupiter WASP-121b has an atmosphere so hot on one side that it breaks down water molecules and rains rubies and sapphires.
The diamond rain phenomenon is believed by some scientists to take place on Uranus and Neptune in our solar system. It is thought it exists some 8,000 km below the surface of our ice giant neighbours, created from commonly found mixtures of hydrogen and carbon, squeezed together at incredible pressure.
Worldwide reserves are estimated to be some 1.2 billion carats. Russia has the largest reserves, estimated at some 650 million carats.
The finding, published in Science, suggests that a reservoir of water is hidden in the Earth's mantle, more than 400 miles below the surface. Try to refrain from imagining expanses of underground seas: all this water, three times the volume of water on the surface, is trapped inside rocks.
The magnificent Cullinan Diamond – the largest diamond ever found- is incorporated into the Crown Jewels. The stone was discovered near Pretoria in modern -day South Africa in 1905, and is named after the chairman of the mining company, Thomas Cullinan.
In our solar system alone, there is an asteroid between Mars and Jupiter named 16 Psyche that scientists believe contains more than 700 quintillion dollars in gold and other precious metals.
Named GJ 504b, the planet is made of pink gas. It's similar to Jupiter, a giant gas planet in our own solar system. But GJ 504b is four times more massive. At 460°F, it's the temperature of a hot oven, and it's the planet's intense heat that causes it to glow.
T he moon might be full of enormous diamond crystals, but they won't do us much good if they're not close enough for the surface for us to get to them. We find diamonds near the surface of Earth mostly because of volcanic activity. Plate tectonics also play a role in transporting deep material to Earth's surface.
In addition, lithium, cobalt, nickel, copper, zinc, niobium, molybdenum, lanthanum, europium, tungsten, and gold have been found in trace amounts.
Diamond rain forms when hydrogen and carbon found in the interior of these planets are squeezed by the high pressure and form solid diamonds that sink slowly further into the interior. The research has been published in the journal Nature Astronomy.
The Diamond Planet is worth 384 quadrillion times more than Earth's GDP. And a mere . 0182% of the Diamond Planet's raw diamonds would handily pay off what the Economist estimates is the $49 trillion in debt held by the world's governments.
Hidden inside the Earth—within the first several hundred kilometers below the crust—there is another ocean. It is, most likely, the largest ocean in the world. This water is not sloshing around in a big pool.
The Lost City Hydrothermal Field, often referred to simply as Lost City, is an area of marine alkaline hydrothermal vents located on the Atlantis Massif at the intersection between the Mid-Atlantic Ridge and the Atlantis Transform Fault, in the Atlantic Ocean.
Bodies have been retrieved almost completely intact from waters below 7°C after several weeks, and as recognisable skeletons after five years. In tropical waters such as the Arabian sea, it's a different story.
Tanzanite. Tanzanite is a shocking 1000 times more rare than a diamond. Discovered for the first time in 1967 and only found in the foothills of Mount Kilimanjaro, these gemstones go for about $1,500 per carat. Tanzanite has the ability to change color depending on the angle of light it is in.
Diamond reserves have been stable in recent years at 2.3 billion carats, a sufficient level to sustain current annual production for the next 18 years. New pipeline and expansion projects along with currently operating facilities will generate around 172.3 million carats in 2025.
So, yes, diamonds can break. This comes with good news and bad news. The bad news is that no diamond is impervious to breaking, but the good news is that it is an extremely rare occurrence.
Did you know that there are storms always occurring in space? Not rain or snow, but winds and magnetic waves that move through space! This is known as space weather.
Glaciers made of nitrogen ice creep across its surface, hazes cycle through its puffy atmosphere, and dark organic compounds rain down.
Uranus holds the record for the coldest temperature ever measured in the Solar System: a very chilly -224℃. The temperature on Neptune is still very cold, of course – usually around -214℃ – but Uranus beats that. The reason why Uranus is so cold is nothing to do with its distance from the Sun.
