That's pretty cool - looks like they are substituting (static pressure and lots of heat) for (a lot of pressure with some 'twist')?

An international team of researchers led by the Australian National University (ANU) and RMIT University in Melbourne, Australia said Wednesday they have created two types of diamond at room temperature by using high pressure equivalent to 640 African elephants balancing on the tip of a ballet shoe.

The researchers said they were able to create two types of structurally distinct diamonds -- one similar to those typically worn in jewelery, and another type called Lonsdaleite, which is found naturally at the site of meteorite impacts and is harder than most diamonds.
I'm not familiar with the 'lonsdaleite' diamonds - I assume it is just structural differences that make them stronger.
