I smell a Chinese scam, if it were so the diamond market would have collapsed. To create diamonds you need laboratory equipment to replicate the creation process at high pressures.
As far as I know, lab-made diamonds are easily identifiable.

They're a bit too perfect, which begs the question of why you would want a natural diamond when you could have these.
