First, the title “What does 'harder than diamond' mean?”, suggests that some materials can be harder than diamond. In fact, so far, no natural or synthesized material has been found to be ...

Microscopic view of hard diamond samples (Nature Materials (2025)) Now, a new study, published in the journal Nature Materials, reports the synthesis of “well-crystallised, nearly pure HD” by ...

China is cutting edges in the field of experimentation and invention. In the latest, China has produced an artificial diamond and is calling ‘super diamond’. This diamond is rare and is ...
