9-mile-thick layer of solid diamonds may lurk beneath Mercury's surface, study hints
New simulations suggest that a 9-mile-thick layer of solid diamonds may lurk deep below the surface of Mercury. The gems almost certainly can't be mined for bling — but they may help solve some of the planet's biggest mysteries.
Argyle mine: Earth's treasure trove of pink diamonds born during a supercontinent's break up
During 37 years of operations, the now-closed Argyle mine produced more than 865 million carats (191 tons) of rough diamonds and 90% of the world's pink diamonds.
Scientists grow diamonds from scratch in 15 minutes thanks to groundbreaking new process
Scientists have used a new technique to synthesize diamonds at normal, atmospheric pressure and without a starter gem, which could make the precious gemstones easier to grow in the lab.
Scientists may have pinpointed the true origin of the Hope Diamond and other pristine gemstones
Researchers suggest that the famed Golconda diamonds, including the Hope Diamond and Koh-i-noor, may have originated from a volcanic outcrop nearly 200 miles from where they were mined.
New diamond transistor is a world-1st — paving the way for high-speed computing at the highest temperatures
Scientists have created an n-channel transistor using diamond for the first time, potentially leading to faster components that can work in extreme conditions.
Rare 'super-diamonds' may already exist on other planets, and could be made on Earth, study hints
A simulated form of carbon called BC8, or 'super-diamond', could be 30% tougher than normal diamonds, but synthesizing it on Earth won't be easy.
Fountains of diamonds that erupt from Earth's center are revealing the lost history of supercontinents
Feature Diamonds seem to reach Earth's surface in massive volcanic eruptions when supercontinents break up, and they form when continents come together.
