Diamonds
-
Researchers have now found evidence that some of the world’s most impressive gems, such as the Hope Diamond and the Cullinan – which adorns the Crown Jewels – originated much deeper in the Earth’s mantle than previously thought.
-
Researchers have created a new ultra-tough structure whose strength had only been theorized previously. The nanoscale carbon lattice made using 3D printing technology boasts a much greater strength-to-density ratio than diamonds.
-
A new type of artificial diamond developed by scientists at Stanford University promises yet another more efficient means of production, with a molecule found in crude oil and natural gas serving as their starting point.
-
Graphene is already known for being incredibly strong, so how can it be made even stronger? By turning it into sheets of diamond, of course. Researchers in South Korea have developed a new method to convert graphene into ultrathin diamond films.
-
A diamond with another diamond that moves freely inside it has been found. Dubbed the Matroyoshka diamond, it's the first known diamond of its kind.
-
Researchers in Australia and Germany have found that many diamonds begin life as sediment on the bottom of the ocean, before being swallowed up by the Earth’s mantle and forged into our favorite shiny stones.

ScienceNanothermometers, while not a brand new idea, are still at the cutting edge of science. We've seen impressive results to date, but accuracy and resolution can always improve, and this is what researchers from the University of Technology Sydney in Australia believe they've achieved.

Diamond is a useful material, but its relative rarity on Earth makes it difficult to get. Now, researchers at NCSU have demonstrated a new way to convert carbon nanofibers and nanotubes into diamond fibers that can be performed in a lab more easily than existing techniques.
-
Rolls-Royce Motor Cars has joined forces with the House of Fabergé to create the first Fabergé Imperial Egg in 101 years. The gold egg decorated with diamonds and amethysts features the luxury car mark's iconic Spirit of Ecstasy hood ornament sculpted from rock crystal.
-
ScienceThe next blow to Big Diamond might have just arrived. Using sound waves, geologists have discovered a gigantic stash of the so-called precious stones deep in the Earth's interior, possibly to the tune of a quadrillion tons.
-
Here on Earth, 80 years of advertising has told us that diamonds are special, but our shiny stones have nothing on the weird and wonderful forms seen out in space. Now, astronomers have found that mysterious microwave signals around stars could be caused by swirling clouds of diamond dust.

Nuclear batteries can last decades, but their power density is currently too low to be very practical. Now, Russian researchers have developed a new nuclear battery design based on nickel-63, which has a higher specific energy than regular, commercially-available batteries.
