Diamonds can now be created from scratch in the lab in 15 minutes
Scientists have revolutionized diamond synthesis with a groundbreaking method that creates diamonds at room temperature and pressure.

Finally. Can I now get a smartphone screen made of diamond please?
And some diamond thermal paste
Wouldn’t that basically just be graphite?
No! good question though, but it misses a detail of their molecular geometry/energy structure.
They're both allotropes (different forms) of carbon but the way they are arranged atomically is different. Like soot is basically just random balls of carbon (??? bonds), graphite is rings bonded in a plane (3 bonds, a single layer of which is called graphene), and diamond is a network that extends in 3 dimensions with each atom bonded to 4 carbon atoms.
When you grind them up you are more making smaller and smaller shards of the base material than changing it's energetic structure, although at the edges it is changing. If you grind pathologically I suppose you would eventually reduce it all to soot.
The physical properties of stuff is in part altered by the surface configuration when we get extremely small, but in general we just consider the bulk as even tensie tiny fragments of stuff are thousands (tens, hundreds of depending on geometry) of atoms, of which only a handful have different bonds at the edge.
I love learning. Thanks for sharing!
