| LARGE DIAMONDS MADE FROM GAS ARE THE HARDEST YET |
| Washington, D.C. Producing a material that is harder than natural diamond has been a goal of materials science for decades. Now a group* headed by scientists at the Carnegie Institution's Geophysical Laboratory in Washington, D.C., has produced gem-sized diamonds that are harder than any other crystals. Further, the researchers grew these diamonds directly from a gas mixture at a rate that is up to 100 times faster than other methods used to date. |
