A Diamond created that’s harder than all found in Nature

Scientists created a diamond that’s harder than all found in nature.

The new diamond predicted to be harder than a jeweler’s diamond and useful for cutting through ultra-solid materials on mining sites.

Dr Jodie Bradby from the ANU Research School of Physics and Engineering, said:

“This new diamond is not going to be on any engagement rings. You’ll more likely find it on a mining site – but I still think that diamonds are a scientist’s best friend. Any time you need a super-hard material to cut something, this new diamond has the potential to do it more easily and more quickly.”

Her research team made the Lonsdaleite in a diamond anvil at 400 degrees Celsius, halving the temperature at which it can be formed in a laboratory.



“The hexagonal structure of this diamond’s atoms makes it much harder than regular diamonds, which have a cubic structure. We’ve been able to make it at the nanoscale and this is exciting because often with these materials ‘smaller is stronger’.”
