Since the 1950s, scientists have replicated these conditions in the lab using high-pressure, high-temperature (HPHT) methods to create synthetic diamonds. But now, a team led by Rodney Ruoff at ...

For gemologists, there are quite a few details to be had when it comes to the markers that help identify lab-grown diamonds - ...

Even so, you end up with raw diamonds that need to be processed in order to become gems or industrial components. For HPHT, you’d also need a bunch of good graphite, catalysts such as iron and ...
