We present evidence of the unique role of metallic liquids of composition MexCyHz (Me = Au, Ag, Cu, etc.) made by reacting mixtures of a metal and carbon in a microwave-stimulated H plasma at pressures near 100 Torr in diamond synthesis. Typical cubo-octahedral diamond crystals can be seen precipitating from such liquids in the temperature range 800-950 °C.
