A UK firm named Skydiamond hopes to revolutionize the standard diamond mining trade through the use of carbon seize expertise to just do that. The corporate calls it a ‘zero-impact diamond’ as a result of the method pulls carbon dioxide proper out of the air. Though, a diamond traps solely a modest quantity of carbon — one carat incorporates simply 200 milligrams.
Pure carbon can take many varieties — all of it is dependent upon how the atoms are organized. Graphite is organized into a number of layers, graphene in a single layer, and if it’s rolled-up, it varieties carbon nanotubes. However when every carbon varieties 4 robust bonds in a tetrahedral construction, it turns into a diamond.
Most pure diamonds had been fashioned over a billion years in the past, greater than 120 kilometers beneath the Earth’s floor. That is the place intense temperature and stress trigger carbon atoms to strongly bond collectively and prepare into crystal buildings. Volcanic eruptions convey these crystals embedded in magma to the floor. When the magma cools, it hardens in lengthy vertical shafts referred to as kimberlite pipes. And these pipes are what’s wanted within the mining trade.

Eco-friendly diamonds comprised of the sky
https://www.bbc.co.uk/newsround/54734306
“t took the crew greater than 5 years to get the method proper, guaranteeing they’re bodily and chemically similar to Earth-mined diamonds. The diamonds – licensed by the Worldwide Gemological Institute — take a few weeks to be made.”
Are laboratory-grown diamonds the extra moral option to say ‘I do’?
https://www.theguardian.com/lifeandstyle/2020/mar/10/diamonds-lab-grown-climate-change
“Diamonds are fashioned naturally by a mix of warmth, stress and time, rising deep underground till deep-set volcanic eruptions convey them nearer to the floor, able to be excavated. Lab-grown variations recreate this utilizing a fraction of diamond in a sealed chamber which is heated to excessive temperatures…”
Why turning China’s smog into diamonds isn’t as loopy because it sounds

“After a pilot in Rotterdam, the Smog Free Challenge is coming to China. The venture consists of two components. First, a 7m tall tower sucks up polluted air, and cleans it at a nano-level. Second, the carbon from smog particles is was diamonds.”
